I really want to help people who are learning Chinese, but it seems that there arelike very few people who are learning Chineseit here.

where is here? you should establish the location first, then from that point forward, you can use "here".

If you are learning Chinese right now, please write essays as many essays as possible, so I can help you with them.

you don't have to use "right now", as that is implied.

Meanwhile, if it's possible, please learn Chinese, I would be happy to help.

This sentence is not necessary. you are basically repeating the same thing as the last sentence.

Thank you guysall very much.

Avoid using "guys". That implies everyone is a man. Instead, use gender neutral words.
