You can find Zhengzhou Long-distance Bus Station near the railway station, so you go walk there to find buses for Dengfeng. The bus leaves from Zhengzhou every 30 minutes. You take the bus to reach its terminal- Dengfeng West Bus Station. Get out of the station, you can find local city bus 8 to reach the temple directly. If you cannot find bus 8, you can take a taxi to reach.

Although you can buy the ticket to reach in the Zhengzhou bus station, but it is not suggested to buy. Because, if you buy that kind of ticket, you may have to travel to other attractions along the road. So, you need to buy the ticket for Dengfeng West Station and then make transfer by yourself.
