I understand the domestic price here as management fee, expected profit and so on, but your price is too low, isn't it? Should it be 13.48 RMB \ \ vehicle (I calculated it according to this figure)? Net foreign exchange income refers to offshore foreign exchange income after deducting freight and insurance premiums, so freight and insurance premiums can be calculated without being converted into RMB.

Export exchange cost = (140+ 13.48) RMB /(42.4-7.84- 1.52) USD = 4.65.

That is, 4.65 RMB can be exchanged for 1 USD, which is very low compared with the exchange rate, indicating that the operating efficiency is very good.
