The rocket does not have landing legs. Could it be that a cable landing will be tested?

It has to be cable landing like CZ-10A.

The previous successful VTVL was carried out with landing legs, so I wonder if they're trying a splashdown recovery this time. Granted I haven't heard anything confirming this, but I also haven't heard anything about a cable landing either. Since the upcoming VTVL test is to be carried out at the Haiyang Oriental Spaceport located on the shoreline, there is a non-zero chance they will land the vehicle in the ocean and tow it back.

This is to test in-orbit refuelling and satellite life extending. Not sure whether Shijian-25 will be the "tanker" or a tanker satellite will be launched later.
