S237 Yuzhou section used to be a famous bad road in Henan Province, and the road condition was good after overhaul in the first half of this year, while 323 did not pass through Yuzhou, but was in Xinmi and Xinzheng.
If you ride a bike, get ready. There are still many trucks and coal trucks along the way, and the road is very dirty. As for mountain roads, there are mountain roads, but there are not many steep slopes.
