Are CCCC No.2 Middle School and China Construction No.7 Middle School the same level?

CCCC Aviation No.2 Bureau and China Construction No.7 Bureau are two large state-owned construction enterprises in Chinese mainland. Although they all belong to state-owned construction enterprises, their levels are not exactly the same. CCCC Aviation Second Bureau is a subsidiary of CCCC Group, a secondary central enterprise, and mainly engaged in traffic engineering construction projects. China Construction Seventh Bureau is a subordinate enterprise of China State Construction Engineering Corporation, which belongs to the first-class central enterprises and is mainly engaged in construction projects. Therefore, in terms of level, the level of China Construction Seventh Bureau is higher than that of China Communications Second Aviation Bureau.
