What is the relationship between Guangzhou Keteng and China Southern Power Grid?

It's okay. According to enterprise inquiries, Guangzhou Keteng Information Technology Co., Ltd. was established in 2007, integrating IT operation and maintenance services, power industry consulting, information system research and development, and project implementation. China Southern Power Grid Co., Ltd. is a central enterprise supervised by the State-owned Assets Supervision and Administration Commission of the State Council, headquartered in Guangzhou, and a super-large state-owned key enterprise related to national security and the lifeline of the national economy. These two companies are independent enterprises and have nothing to do with each other.
