China ATC restrictions not only cover flights between PVG/PEK, but all aircrafts passing through China Airspace....

The incoming CX253/25 Aug (STD: 1435HKT) was indeed delayed by around 4 hours. However, I couldn't find any CX flights from PEK/PVG in the morning to early afternoon hours of 25 Aug being significantly delayed.
Flightradar also didn't show B-KQU, the aircraft concerned, operating a mainland China sector on 25 Aug.
Am I missing something?
