All aspects of the Han nationality are forbidden to ask the Great God for help.

Most Han people avoid eating raw food on the first, second and third days of the first month, that is, the food on the first day of the New Year's Day is much more cooked than before the old calendar year, and it only takes three days to return to the pot. I think it's ripe and smooth, but my life is reverse. Therefore, in some places, everything is ready before the Spring Festival, and there is a saying that the knife can't be cut for three days. For another example, in some areas of Henan, the third day of the first month is Xiaomi's birthday, and rice is not eaten on this day, otherwise it will lead to millet production reduction; In the past, women had many dietary taboos during childbirth. For example, women in many areas of the Han nationality do not eat rabbit meat during pregnancy, and think that children who eat rabbit meat will have rabbit lips; In other places, it is forbidden to eat fresh ginger, because fresh ginger has many fingers, so as to prevent children from growing six fingers on their hands and feet. In the past, most childless women of Han nationality avoided eating dog meat, thinking that it was unclean and easy to cause dystocia. In the long-term historical development, the Han nationality has integrated the excellent cultures of all the fraternal nationalities, and also accepted some national customs, forming its own unique etiquette and customs taboos, mainly including: 1, avoiding wearing white clothes on holidays. In Dai Xiao, it is considered unlucky to wear white clothes after the death of a relative. Of course, modern people get married except the bride's white wedding dress. 2. Don't say "13" to others, which is to look down on other people's dirty words. 3. Avoid saying that men are "turtles". If so-and-so is a "turtle", it is equivalent to calling him a useless man who doesn't even care if his wife has a third party. 4. Avoid using the word "4" in many places. Because "4" and "death" are homophonic, for example, the number of patients and beds in some hospitals should not be numbered with "4"; Some buildings don't use the floor and room number numbered "4", but use "13B" instead of "14" floor. 5, men and women in love, avoid eating a "pear", because "pear" and "parting" are homophonic, as well as visiting the patient's fruit, avoid giving "pear", the same reason. 6. When you move to a new house, it is forbidden to "send the clock" on your birthday, because "send the clock" and "send the final" are homophonic. If you use a "clock" as a gift, you should say "send a timer". As a settled agricultural nation, Han people not only pay attention to the residential function of houses, but also closely link houses with the fate of "home". Every family and clan wants to grow and develop. In order to achieve this goal, people make a big fuss about housing construction, trying to choose Long Mai with geomantic omen and God-blessed areas to build houses. However, the location, orientation and furnishings of some houses are not in line with Feng Shui. The concept of "xiangzhai" is listed as taboo. Site selection, commonly known as "fragrant mansion", is the choice of objective things and environment, which can be described as the premise of architecture. Among the Han people, agricultural production has a strong dependence on climatic conditions and natural environment, and gradually gives nature a high degree of spiritual symbolic significance, thinking that the quality of natural environment will directly lead to the quality of people's fate. So it is very important to choose a good foundation in architecture.
