About Genshin Impact: to export your soft power to people abroad, you first need to sell it out to the people abroad. People are influenced by the US's soft power because Hollywood does(did?) make a lot of good movies. Besides, Genshin Impact does have a lot of Chinese elements in it, just so many comments here regarding modern Chinese people's lives as a totally different one from the west. Like we Chinese people should live in another way although we use the same tools like phones and computers. Many of the so-called 'real' Chinese cultures are just outdated if not dead already as many cultures in the west. Many of these cultures, which are lucky enough still exist in modern china, changed a lot.
One example here:
This Peking opera video get more than 80k views from western players after one story quest of Genshin Impact was released which is about Peking Opera. Here is the first comment I see under that video:
Actually, the Peking opera shown by Genshin Impact is a more acceptable version of it, because it is just too costly and too long to put a whole scene into that chapter of Genshin Impact. (Btw Peking Opera is really good for people who can read and listen Mandarin Chinese, I have heard it many times.)
Mihoyo is influenced by western and Japanese culture, they do have girls(and boys) in western and Japanese styles. But they also have characters in many other styles. Like Japan, China, Egypt, Western, India, and so on. I think they are doing quite well in exporting soft power.
