Hey I am meeting my gf can I know what places will be more romantic in Zhengzhou

You are suggested to go to Fantawild Adventure or The Happy Century Garden. Also, Nongke Rd and Jiangkang Rd are good places for you to enjoy the night market.

Actually, during the Sep, when the temperature in ZZ is not so freezing, a picnic in the park surrounding the Long Hu Lake located in the north part of the Zhengdong New District will be a good choice. Because that area is not so crowded before the buildings are finished, and I do like that lake!! Just go there by cycling and remember to explore a certain route before starting the trip. OHHH, BTW, just take a piece of picnic cloth, the food made by yourself and some books you both like. Wish you have a good time.
