My dad owns an oil company in China, but he just decided to dissolve the branch company in US due to the falling petroleum price.

He has the following questions:

1 how many years could the accounting file of the dissolved company be preserved after the firm had been cancelled or how long is the retention period after the accounting file formed? (Please be as specific as you can)

2 what kind of law prescribe the rule asked by question above? Please give me the link.

3 does the dissolved branch company have the right to destroy its accounting files or does it have the rights to hand over the file to the shareholder of the general company? Anyway, what would be done to the accounting file of the dissolved company?

4 what kind of law prescribe the rule asked by question above?

Only need to answer 4
