What would be the reason for testing an already in production engine? Have they done any modifications to it?YF-100K development continues apace. The engine has conducted its first hot test run of 2025.

It's an uprated variant for the upcoming Long March 10 moon rocket.
The YF-100K is an uprated variant of the YF-100. Is the YF-100K used on the LM-10 any different from the YF-100K used on the LM-12?

LM-12 uses the YF-100L variant. As far as I know, the major difference between it and the YF-100K is that the latter is gimbaled. There might be other differences, but I don't know the specifics.
It should be YF100-J, J gimbals at one X direction. K gimbals at two X&Y directions.
There are also some upgrades to the second stage rocket, i.e. the section material, and the fuel tank design.

More detailed information on the manned lunar rover project. After two rounds of expert assessment of various submitted proposals, two designs have been chosen for prototype development. One is being developed by Shanghai Academy of Spaceflight Technology (SAST) and the other by a subsidiary of CASC. The two prototypes will be pitted again each other, and the winner will be sent to the moon. China Manned Space Agency is now soliciting the public for names for the manned rover.
According to Mr. Zhang Chongfeng of CASC, the proof-of-concept/demonstrator manned lunar vehicle being developed by CASC has finished testing at lunar surface simulation field. The project is now moving onto initial prototyping stage.
