On April 22, the name campaign of the 10,000 meter manned submersible was officially launched on CCTV news client, Weibo and WeChat. As soon as the activity launched, a wave of "name talent competition" was set off on the network. After receiving the names of nearly 100,000 netizens and a fierce battle, the top ten names of the activity were released. After the evaluation by the group composed of the overall experts group, the owner unit and the scientific research team, the name of the submersible was finally released: “fendouzhe".

“fendouzhe" is in line with the spirit of the times, fully reflects the spirit of contemporary scientific and technological workers who continue to struggle and climb to the peak, and conforms to the image of the "most beautiful fighter" of China's manned deep-sea diving team. Therefore, the "fendouzhe" is selected as the name of the deep-sea manned submersible in the list of ten names.

The "fendouzhe" submersible has successfully completed a tank test. The submersible has simulated various working conditions in the ocean environment in the tank and has carried out various tests. Finally, the tank test results show that the submersible has good performance and stable state.
