hi guys, i'm not sure whether this is the right place to ask. but i think it's about money management too.

basically, i'm going to be sent to work in china by my current company. So, i want to ask how and where should i declare my income TAX? i'm wondering should i ask my company to pay me in RMB or RM. whichever that can enable me to pay less tax

i heard that if i'm going to work oversea, i would consider expat and need to pay 26% flat rate! is that true?

it's welcome too if anyone can advise me about China income tax rate. i've searched google and come back with many different result.
