手机发的，不知道怎么放悬赏币=_=能给点好建议的一律回馈30论坛币。（自己随便传个文件，设置卖价30，我去下载就相当于回馈了）

Hello buddy,

Here is my suggestion,
find an insider (either your friend's friend or classmate's classmate) and ask what about your concern.
You need truth.

Setup your goal and your budget.
It's a project with limited time buffer.
You won't be young any more, especially after several rounds of trials.

Last,
keep safe and
take care,

Thanks for your relevant suggestion！I'll keep it in mind！
