Where is Zhengzhou Cai Zhao?

The address is north of Buchang Street, Longhai Road 100 meters. When you get off at the railway station, you actually go south along Yima Road or Qiaojiamen Road, and then go east at Longhai Road. Cross the first intersection turning south, which is Buchang Street, and you are almost there. It's only about two stops. If you want to take a bus, I can also list the trains for you.

105 north line, ok, this bus is divided into north and south lines. You should take the north line, take 2 stops, and get off at Buchang Street Station on Longhai Road, just across the road.

Or take bus no.206, which is also two stops.

The third is the 729 bus, which takes three stops.
