I wanna find a place to upload my translation and get feedback or suggestion

Hello, you may try http://www.now-do.com
It's a social platform for translating novels and comics. Plenty of authors publish their stories and wish them to be translated into different language. The translators are from anywhere of the world. They always give suggestions while translating and reading.

I was writing a thesis recently and perhaps you can get feedback or even assistance where I got thesis help last week.
