The future development direction of Zhangjiakou is definitely high-tech zone. In addition, universities and middle schools in Zhangjiakou are moving to the high-tech zone. I suggest you go to the high-tech zone for development. At present, it is very painful for students to eat at school, and the food in the canteen is not delicious. If you go late, you won't have it. You can open a restaurant, but it must be economical and affordable for students. Besides, you can have a barbecue or something in the evening. I've considered doing this, but I can't help it if I'm not at home. In addition, you can choose internet cafes, logistics and the like, hehe, good luck!
