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

most of the Han people avoid raw food on the first, second and third days of the first month, that is, the food cooked on the New Year's Day is more than that cooked before the old calendar year, and they only need to return to the pot for three days. It is thought that familiarity is smooth, and life is contrary. Therefore, in some places, everything was prepared before the new year, and there was a saying that knives and scissors were not moved during the three days of the festival. For another example, in some areas of Henan, the third day of the first month is the birthday of millet, and rice is not eaten on this day, otherwise it will lead to the reduction of millet production; In the past, there were many dietary taboos during women's childbearing. For example, women in many areas of Han nationality do not eat rabbit meat during pregnancy, and think that children who eat rabbit meat will have rabbit lips; In other places, fresh ginger is forbidden because it has many fingers, lest children grow six fingers on their hands and feet. In the past, childless women of the Han nationality mostly avoided eating dog meat, thinking that dog meat was unclean, and it was easy to cause dystocia after eating. In the long-term historical development, the Han nationality has integrated the excellent cultures of various brotherly nationalities, and also accepted some national customs, forming its own unique etiquette and customs taboos, mainly including: 1. Avoid wearing white clothes on festive days. It is considered unlucky to wear white clothes in Dai Xiao after the death of a relative. Of course, modern people get married with the exception of the bride's white wedding dress. 2. Don't say "13 o'clock" to others, which is a swearing word that looks down on others. 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 of the homonym of "4" and "death", for example, the number of patients and beds in some hospitals should not be numbered with "4"; Some buildings do not use "4" numbered floors and room numbers, but use "13B" instead of "14" floors. 5, men and women in love, avoid eating a "pear", because of the homonym of "pear" and "separation", as well as the fruit of visiting patients, avoid giving "pear", for the same reason. 6, moving to a new house, birthday taboo "send the clock", because "send the clock" and "send the final" homophonic. If you use a "clock" as a gift, you should say "send a timer". As a settled agricultural nation, the Han nationality not only pays attention to the residential function of houses, but also closely links houses with the fate of "home". Every family and family wants to grow and prosper. In order to achieve this goal, people have made a great deal of fuss about the construction of houses, trying to choose areas with geomantic Long Mai and god's blessing to build houses. However, the location, orientation and furnishings of some houses do not conform to geomantic omen. The concept of "Xiang Zhai" is listed as taboo. Choosing an address, commonly known as "xiangdi", 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, it gives nature a high degree of spiritual symbolic significance, thinking that the quality of natural environment will directly lead to the good or bad fate of people. Therefore, it is very important to choose a good foundation in architecture.
