What's really interesting is not the fight itself, but the fact that Chinese robot companies have commoditized humanoid robots that are capable of acrobatics already.
You can buy an off-the-shelf humanoid robot that has everything needed to balance, move with both feet off the ground at the same time*, get up from being knocked over etc. All the sensors, joints, and software needed to make it happen are there, you just need to teach it some fighting/dancing/labour moves.
* This demonstrates a high level of advancement. Older/shitter robots like Elon Musk's Optimus look constipated because they have to be balanced on at least one foot at all times. Boston Dynamics pioneered robots that can, like humans, throw themselves off balance and catch themselves. Both feet can be off the ground at the same time, and to walk or run like a human it's a requirement to be able to essentially fall forwards and catch itself on the leading foot.
