There are many players in China, why not support Chinese?

If it can support Chinese, it will gain the support of many players. When will Chinese be added? Up to now, there are still games that do not support Chinese, which makes me very incomprehensible. After all, many games have gained more players because they support Chinese. I thought it would support Chinese, so I bought it, but when I downloaded it, I found that it still didn't support Chinese, and I returned it directly. As far as I know, many Chinese players have returned it because of this.
