1. Certificate of cancellation of foreign exchange after inheritance (statement is relatively complete)
2. Certification Form/Certification (Literally, customers who don't know the cancellation procedure won't understand)
3. Tax refund documents/vouchers (the meaning is more accurate for exporters, but sometimes I don't want foreign businessmen to know that exporters can refund taxes)
4. Foreign exchange control declaration (more accurate from the perspective of foreign exchange control)
