Tang Ningshan closes these documents and then looks at the logistics manager and asks "Is the bank card you used for purchasing things the special bank card that the company specially opened for this project?" After listening to Tang Ningshan's words, the logistics manager takes out a bank card from his pocket and hands it to Tang Ningshan. He says "General Manager, I don't know if this card is a special bank card for this project. Anyway, I have been using this bank card since I worked as the logistics manager of this project. Every time I purchased the raw materials from the same company according to the requirements of my head. Also, every time after I receive the funds, I will record the amount and time on this cash flow statement.
