Seeking Arrangement is translated into Chinese Simplified (https://www.seekingarrangement.com/zh) and Chinese Traditional (https://www.seekingarrangement.com/zh-tw). So there is a website for Sugar Daddy / Sugar baby dating.

我 我 我 不知道. Maybe there would be many 假的 sugar daddies? Do you really think so many Chinese girls are like this? 你确定吗?

I don't live in China and I am sure that you know more about your government's regulations than I do.

First of all, I would like to re-write your paragraph from above so that it appears in perfect English. If I may.... "Why doesn't China allow websites like "seeking engagement? Recently, I found a website named "Seeking Engagement"; I am curious about why so many young women are searching for a "sugar daddy".... Why do Chinese people not have such websites? Is it because of government regulation of what people can see and do on the internet??" I hope this helps you in your learning of English.
