If you can do the relevant procedures of export tax rebate yourself, you don't need to find a tax agent unless you can't afford to learn for a long time! The staff of our export tax rebate management section are very careful to teach you how to do it! If you are mistaken! Ask again! If the tax authorities force you to find an agent, you can ask their leader.
I hope you can do your own export tax rebate work happily and smoothly!
