Various companies, including the state-owned China Aerospace Science and Technology Corporation plan on launching reusable rockets in the coming years. CASC's announcement was made yesterday. Before then, I believe they only had plans to make the Long March 9 superheavy rocket reusable in the 2030s? Or maybe I missed some news a while back. China's space industry is very convoluted. I should probably make a master post about it sometime for everyone's sake.
Dong long (east dragon) would actually make sense though. There's already a dong feng (east wind) rocket.
