The period of earning foreign exchange is the period of earning foreign exchange by exporting overseas. There are mainly two periods, one is 49 to 60 years old, and the other is 70 to 80 years old. Everything stopped in the middle because of historical reasons, so there was no production. The previous era was also called the initial stage of earning foreign exchange. All the products circulating in our market were produced in the 1970s and 1980s. Now we have added the second period of earning foreign exchange through export in the 1970s and 1980s. During this period, many domestic and exported craft products basically followed the style of the Republic of China.
