The Datong Hotel is okay, just a bit expensive!
The north exit of the train station is about a kilometer to the left and west when you get to the bridge [s:3] I haven't measured it either~
Looking up, there's a newer Kaikai Express Hotel that's not too bad, and a standard room is about 120~ I can't remember~ [s:4]
You can call to make a reservation, I think.
A little further west there's a Zhengzhou sign, Heji, with a nameplate that says, ``Chow Mein'. The first one is the Yangji Ramen, which is also good. There is also a hot pot, and there is also a shabu shabu restaurant north of the intersection, which is quite good. ~~~~~ hahaha Although I'm not from Zhengzhou, but my boyfriend is, he has taken me to eat all over there.
Why don't you find a place to stay in the area around the test site? [s:3]
