In china is there arranged marriage

Well, yes, there is. Especially in some remote areas, the arranged marriage is more common.

In which city of china, they do still arrange marriage let me know it is urgent.

Arranged marriages are very common in China, especially in more remote areas (which is fairly a lot considering the size of the country). There is no "one" city. Arranged marriages have been the norm for thousands of years; I wouldn't be surprised if most Chinese families expected their sons/daughters to get married this way even now.

They do arranged marriages in most cities, here in Zhengzhou, I know of a park where every Saturday match makers and parents are out in the park trying to arrange a marriage.
Along with fortune tellers to help decide if the match may be good.

i was wondering how many kids can you chinese people have?
