iIf someone gave me $100 million, what would I do with it? If someone gave me $100 million, what would I do?

Capital letters at the start of sentences. Since - in the passage - you don't say what you would do *with the money* but instead say what you would do generally, you should remove the "with it" of the money.

I willould travel to China to learn Chinese... I would travel to China to learn Chinese.

I willould travel to China to learn Chinese... I would travel to China to learn Chinese...

(From your title) "If somone gave" is a conditional statement, so you should use "would" here too since it' sconditional. If your title sais "If somes *gives* me...", then you should use "I will travel..." here. Hope that makes sense.
