What is the relationship between Broadcasting Express and Express Digital?

Yuntong Digital Space is a shareholding company of Guangdian Yuntong Company. In 2022, although it was transferred at a low price, it became an absolute shareholding. However, after the completion of the equity transfer, Express Digital Space is still a shareholding company of Radio and Television Express Company, and this equity transfer accounts for a small proportion of the company's total assets, so Radio and Television Express owns the equity of Express Digital.
