Searching the
Wiki 737 accident list, the cloest I can find that has "China" in the description is
China Southern 3456, though it doesn't claim the skipper was incapacitated, rather, they had a hydraulic failure after touching down off the runway and bouncing, then going around for another attempt.
The only other ones there are Xiamen 8301, a hijacking that collided with other aircraft on landing,
China Southern 3943 that crashed on descent due to mismanaging the autothrottle and China Airlines 120, the one that had the fuel leak on landing and exploded at the gate.
