I was born in Henan and later moved to Wuhan. So I belong to Wuhan or Henan.

Native place refers to ancestral home (ancestral home) or native place, and ancestral home is the birthplace of an ancestor in a certain period recognized by a family group. Some people who have left their ancestors' birthplace or hometown still trace their descendants back to their ancestors' birthplace or hometown (that is, ancestral home) as their birthplace. Country of origin refers to a person's original place of origin before moving to a certain place. The domicile is not necessarily the person's ancestral home or native place, especially in economically developed areas, some new places that started construction after the founding of New China and places that have developed rapidly since modern times. A large number of people's native place is not their domicile place. Generally, these people moved from other places to new places after China's reform and opening up or in the era of planned economy, according to the distribution of countries at that time or in modern times. According to the tradition of China for thousands of years, native place is an expression of ancestral place, which is the difference between modern household registration and native place. According to the document of the Ministry of Public Security [1995]9 1, a citizen's native place should be his grandfather's place of residence (domicile) when he was born; If grandfather died, fill in the location of the household registration at the time of grandfather's death; If the grandfather has not left the permanent residence, fill in that the grandfather should leave the permanent residence; After a citizen registers his native place, if his grandfather moves his household registration, his native place will remain unchanged. At present, the frequency of using native place is still very high, but especially young people don't pay much attention to it. They generally mistakenly believe that their native place is their place of residence or birthplace. According to the tradition of China for thousands of years, native place is an expression of ancestral home. Since modern times and since the reform and opening up, there have been a large number of floating population and population migration in China. It is wrong for a large number of people to regard their parents' native place as their own without knowing or forgetting their native place. The domicile refers to the domicile of a citizen with China nationality before the age of 18, that is, the birthplace (according to the latest geographical division) or current residence, not the birthplace of his father or mother, nor the birthplace of his grandparents. And the "ancestral home" should be traced back to which generation, usually ancestors. For example, Zhang San's previous hukou was in Sichuan, his birthplace was in Hubei, and his ancestral home (grandfather's generation) was in Hunan. Now his registered permanent residence has moved to Beijing. To be exact, his native place is Hunan. XXX people are commonly used, where XXX refers to someone's native place, not his domicile place, such as "Hunan people", which means that someone's native place is Hunan, but not his domicile place is Hunan. According to your description, your domicile place is Henan, but your domicile place is Wuhan, Hubei. Your grandson can write Wuhan, Hubei when he fills in his birthplace.
