However, it doesn't mean that there isn't. The first training institution in China, Chinese Business International Management College, is a professional research and training institution in this field. He has made great achievements in the construction of internal control system, internal control system and internal control mechanism, and is well-known and influential in the market. Southern Building Materials, Shenzhen Development, Guangdong Nuclear Power and other enterprises have introduced their research results and achieved good results.
