It’s not that there are so many people from Henan on Douyin. First of all, Henan has a large population base in the country. Moreover, Douyin recommends things based on big data based on personal preferences. If you watch a video of a Henan person, the platform will continuously push short videos of Henan people to you, which will give you an illusion that there are actually many people registered for short Douyin videos all over the country.
