Zhang Qinghe traveled from the 21st century to 1970 and became an educated youth in Beidahuang.
At this time, Beidahuang was not the Beidacang familiar to later generations. Instead, the sky was blue, the land was vast, roads were broken by ice and snow, roads were blocked by firewood, poisonous insects were forming, and beasts of prey were swarming.

Intention: Vast world, great achievements
