Hello Dave,
China uses a metric system for flight levels and publishes a Flight Level Allocation System indicating required levels.
In your example 1070 = 10,700 meters. As many aircraft systems do not display altitudes in meters there is a conversion table which when referenced for 10,700m would convert to 35,100 feet.
FLAS may differ in other countries airspace so the China’s metric system may not match another.
