Shanghai was once the central city of China's textile industry, the birthplace of modern textile industry and the scientific research and education base of China's textile industry. There are not only textile mills, but also textile science research institute, textile university, textile science and technology information group, printing and dyeing research institute, clothing research institute and other institutions. Although I don't have the specific data of 1992 on hand, I used to be a technician in the silk industry, and I have the national directory of silk enterprises and institutions of 1990 on hand. There are hundreds of silk enterprises and institutions in Shanghai. Silk is only a very small part of textile, and more and more are cotton textile, knitting, linen textile, clothing enterprises and so on. So it is certain that the total number of textile units exceeds 1000.
