Jia said he was thrilled to see the Olympic flag again. "I will work hard in training and try my best again at the Beijing Winter Olympics," he said.

Yanqing, 74 kilometers northwest of central Beijing, will host five events in 2022, including Alpine skiing, bobsleigh, skeleton and luge. Two others locations for Olympic venues will be north of urban Beijing and in Zhangjiakou in the adjacent Hebei province.

The PyeongChang 2018 Winter Olympics closed on Sunday after 17 days' competition. The Olympic flag was handed over by International Olympic Committee President Thomas Bach to Beijing mayor Chen Jining, at the closing ceremony.
