Please help me to check my essay

Hello this is my first time to use this app, I found this app in ZhiHu ，which is a Chinese website focus on solving various problems, ZhiHu looks like Quora, although I haven't try Quora because of vpn restrictions. In the future I think I will use this software more often to learn English and make friends. It is really a perfect app for people who want to learn a new language right? Hope someone warm-hearted look at me ! Please
