There is n train from Wuchang Station to Zhengzhou, and there is also a bullet train. If the students are half price, it won't cost much for you two to go back and forth! Zhengzhou Railway Station is the center of the city. There are many wholesale markets, but there are mixed fish and dragons. Pay attention to property safety. There is nothing to play in downtown Zhengzhou. You can go to Century Happy Garden to find some excitement. The student ticket seems to be 100. You can check the bus from the railway station to Century Happy Park. Then we can arrange to go to Kaifeng. I think it's convenient to go to Kaifeng by train. Although there are intercity buses, the time is too long, and it only takes 45 minutes by train. Moreover, there are many trains passing through Kaifeng, from 5.5 yuan to 1 1 yuan.

When you arrive in Kaifeng, you can enjoy yourself. There are many scenic spots in Kaifeng, but they are all concentrated. If time is tight, you can finish all the competitions the next day, but it is estimated that you will miss Kaifeng's delicious food (mainly night market), Long Ting Park, Tower Park, Qingming Shanghe Garden, and finally Kaifeng House (in Baogong East Lake). In the evening, you can go to Xisi Square (in Baogong West Lake) to taste Kaifeng Night Market, and then buy it the next day.

I am from Kaifeng. I can elaborate on the Kaifeng part, but I haven't been to Luoyang several times and I can't help you.

Kaifeng, Zhengzhou and Luoyang are three cities along the Yellow River from east to west. The traffic is very convenient. I hope it helps you!
