If you name your son in the United States, you can directly add a small number in front of the father's name, because in the United States, he can directly add a small number in front of his son's name. In the United States, it is no different than in China. If you were in China, you would not be able to add "small" directly in front of your father's name. The names are different in each country, so it's fine in the United States.
