Chinese pregnancy traditions: customs, beliefs and what the evidence says
Chinese pregnancy customs draw on thousands of years of Traditional Chinese Medicine (TCM), Confucian family values and regional folk traditions. They vary considerably between mainland China, Hong Kong, Taiwan, and Chinese diaspora communities around the world. For expectant parents navigating both their cultural heritage and modern maternity care, it helps to understand where these traditions come from, which ones are genuinely beneficial, and which carry no medical weight but still deserve respect as family and cultural practices. This article walks through the main categories of Chinese pregnancy customs and looks at what the evidence does and does not say about each.
The roots of Chinese pregnancy customs
Traditional Chinese Medicine frames the body in terms of balance between opposing forces: heat and cold, yin and yang, excess and deficiency. Pregnancy is seen as a period of heightened sensitivity in which the mother's physical and emotional state directly influences the developing baby. This framework underpins many dietary recommendations, activity restrictions and lifestyle beliefs that are still widely followed today. Alongside TCM, Confucian traditions place great importance on the mother's moral character and social conduct during pregnancy, reinforcing the idea that how a mother lives and thinks has lasting consequences for the child. Over time, these overlapping systems have produced a rich body of customs that are observed to varying degrees depending on the family, region and generation.
It is worth noting that Chinese pregnancy practices are not uniform. A family in rural Sichuan, a family in Hong Kong and a family in the Chinese diaspora in the United Kingdom may observe quite different subsets of these customs. Some families follow them closely; others keep only a few; many blend traditional practices with contemporary medical advice. Understanding this diversity prevents oversimplification.
Tai jiao: nurturing the baby through the mother's experience
Tai jiao, often translated as "foetal education" or "prenatal education," is one of the most distinctive concepts in Chinese pregnancy tradition. The underlying belief is that a mother's thoughts, emotions, sensory experiences and conduct during pregnancy shape the baby's character, temperament and even intelligence. In practice, tai jiao encourages pregnant women to listen to classical music, read poetry and literature, engage with beautiful art, think positive and virtuous thoughts, and maintain emotional composure. Activities associated with negative emotions, conflict or moral lapse are discouraged on the grounds that they may harm the baby.
From a clinical perspective, the specific developmental claims of tai jiao are not supported by robust evidence. However, the general principle of promoting maternal wellbeing is well grounded. Chronic stress during pregnancy is associated with negative outcomes, and practices that help a pregnant person feel calm, supported and emotionally balanced are genuinely valuable. The TCM and Confucian framing is different from the biomedical one, but the underlying goal of a calm, healthy, emotionally supported pregnancy is one that both systems share. Parents who find meaning and comfort in tai jiao practices are doing something that is, at minimum, harmless and potentially beneficial.
Dietary customs: warm foods, cool foods and what actually matters nutritionally
Food is central to Chinese pregnancy traditions. TCM classifies foods as having warming or cooling properties, which are distinct from actual temperature: these are energetic qualities attributed to ingredients based on their perceived effects on the body. During pregnancy, warm foods are generally favoured because pregnancy is considered a time when the body needs warmth and nourishment. Cool foods are more likely to be restricted, particularly in the first trimester when the body is seen as especially vulnerable.
Foods that are commonly recommended in Chinese pregnancy culture include congee (rice porridge), red date tea, ginger, longan fruit, eggs and fish. Red dates in particular are popular for their warming quality in TCM and their real nutritional value: they are a source of iron, which is an essential nutrient during pregnancy. Ginger is widely used to ease nausea in early pregnancy and there is some evidence to support its effectiveness for this purpose. Eggs and fish are excellent sources of protein and other important nutrients, including omega-3 fatty acids in oily fish.
Foods that are more likely to be avoided include crabs and shellfish, which are classified as cold in TCM. Interestingly, avoiding raw shellfish also aligns with mainstream food safety guidance, including that provided by the NHS, because raw or undercooked shellfish carries a risk of harmful bacteria and viruses. Very cold foods and drinks, especially in the first trimester, are also often restricted. From a nutritional science standpoint, the warm/cool categorisation does not map onto any known biochemical framework, but many of the foods associated with "warm" status during pregnancy happen to be nutritious choices regardless.
The nutritional priorities that are most important during pregnancy remain consistent regardless of cultural background: adequate iron (to support the baby's development and prevent anaemia), folic acid (ideally taken before conception and through the first trimester to reduce the risk of neural tube defects), vitamin D and a varied diet that includes plenty of fruit and vegetables, protein and wholegrains. Anyone with questions about how to meet these needs while following cultural food practices should speak to their midwife or a registered dietitian.
Activity taboos and household restrictions
A number of Chinese pregnancy traditions relate to activities and household behaviour rather than food. Some families advise against using scissors, especially near or on the bed, during pregnancy. Another common tradition discourages rearranging furniture, hammering nails or undertaking building work in the home. These are sometimes framed in terms of disturbing the energy of the space or the baby's position. Others advise against attending funerals or other events associated with negative energy or misfortune.
None of these activity restrictions have any established medical basis. Rearranging furniture or using scissors does not affect a pregnancy. That said, many of these restrictions have a practical dimension worth acknowledging: heavy lifting, exposure to certain chemicals during home renovations and prolonged standing on ladders are genuinely inadvisable in pregnancy for straightforward physical reasons. Where a traditional restriction overlaps with common sense, there is no harm in following it.
The restrictions that are purely symbolic carry no risk either way. For expectant parents from Chinese backgrounds, deciding which traditions to observe is a personal and family matter. Following them causes no harm, and for many families they provide a sense of structure, community and connection to heritage during what can be an anxious time.
Avoiding baby purchases before the birth
In many Chinese families, it is customary to delay buying items for the baby until after the birth. This is rooted in a belief that preparing too early tempts fate or attracts bad luck. The tradition is sometimes observed strictly and sometimes loosely, with families buying items but keeping them outside the home, or avoiding certain categories of purchase while stocking up on others. As with many folk taboos across different cultures, the belief is protective in intent: it acknowledges the vulnerability of pregnancy and the uncertainty that surrounds it.
There is no clinical reason to avoid purchasing baby items at any point in pregnancy, and many families find that preparing in advance reduces stress in the final weeks. At the same time, families who prefer to wait should be supported in that choice. The emotional and psychological benefits of feeling in control of your own pregnancy experience should not be dismissed.
Regional variation and diaspora experience
It is important not to treat Chinese pregnancy customs as monolithic. Practices in mainland China differ from those in Hong Kong and Taiwan, and diaspora communities in the UK, Australia, North America and elsewhere may observe a mix of traditions shaped by their specific regional heritage, generation, degree of cultural connection and the influence of the mainstream health system in their country of residence.
Midwives and healthcare professionals caring for pregnant people from Chinese backgrounds are encouraged by bodies such as the NHS to provide culturally sensitive care: this means asking open questions about what customs a patient is observing, understanding the reasoning behind them and working with rather than against cultural practices wherever they are safe. For patients, it is equally important to raise any food practices or restrictions with your midwife so that nutritional needs can be assessed and supported.
Frequently asked questions
What is tai jiao?
Tai jiao (foetal education) is the belief that a mother's mental state, what she reads and listens to, and the emotions she experiences during pregnancy shape the developing baby's character and intelligence. Practices associated with tai jiao include listening to classical music, reading poetry, meditation and maintaining positive thoughts. While the specific claim that content can be transmitted to the fetus is not clinically supported, practices that reduce maternal stress and promote wellbeing have genuine benefits.
Should I avoid crab and shellfish during pregnancy in Chinese tradition?
In Chinese traditional belief, crab and shellfish are considered cooling foods and are sometimes avoided during pregnancy, particularly in the first trimester. From a medical perspective, fully cooked shellfish is safe in pregnancy. Raw shellfish carries a risk of bacterial or viral infection and is generally advised against. If your family tradition is to avoid shellfish entirely, there is no nutritional harm in doing so, provided you get protein and omega-3 fatty acids from other sources.
Is soy sauce harmful during pregnancy?
No. The traditional belief that soy sauce will darken the baby's skin has no medical basis. A baby's skin colour is determined by genetics. Soy sauce is safe to consume during pregnancy in normal culinary quantities. It is high in sodium, so very large amounts are not recommended for general health reasons, but small amounts used in cooking are not a concern.
Why do some Chinese families avoid buying baby items before the birth?
Many Chinese families consider it bad luck to purchase furniture, clothing or equipment for the baby before the birth, as it is thought to tempt fate. This is a cultural belief with no medical basis. From a practical standpoint, having essentials ready before the birth can reduce stress in the newborn period. Families who prefer to wait can often receive help from relatives or arrange rapid delivery of essentials after the baby arrives.
