What is the relationship between Guangdong Lianxing and CNNC 5?

It's okay. Guangdong Lianxing is a subsidiary of Guangdong Lianfa Investment Group Co., Ltd., mainly engaged in investment and development in energy, chemical industry, real estate and other fields. CNNC V means that China Nuclear Industry Fifth Construction Company is an engineering construction enterprise under China National Nuclear Corporation, mainly engaged in the design and construction of nuclear energy. Is two independent enterprises, engaged in different fields of operation and development. Therefore, Guangdong Lianxing has nothing to do with CNNC 5.
