Is there any bus from Xinzheng bus station to Yuntai Shan ? direct bus in Henan Province?

There is no direct bus between the two places, so you need to take bus from Xinzheng Bus Station to reach Zhengzhou. Then you can take a taxi to reach Central North Station, which is about 300m north from Zhengzhou Train Station. There you can find two buses for the mountain at 16:30 and 18:00 everyday.
