i asked this question for a long time, why no one try to answer me, i dont wanna just have a certificate, i wanna know how is it, how CFA works. if someone know it ,please give me a feedback. thank you .

中国和其他国家得工作经验怎么算，

The experience in other country counts!

是什么才算相关，会计，审计之类得可以吗，

会计，审计 will not count. Investment, equity research, business valuation, corporate finance ... if you work as financial analyst in corporate, it will count

还有现在考 完，123 LEVEL至少3年，如果边考边工作的时间算不算，

算!

最后怎样计算并核准呢？

Ask other CFA and your boss to sign the form for you. Your boss is not necessarily a CFA.
