Zhangjiakou's future development direction is definitely high-tech zone. In addition, universities and middle schools in Zhangjiakou are moving to high-tech zone, so I suggest you develop in high-tech zone. At present, it is very painful for students who are building a college to eat at school, and the food in the canteen is not delicious. If you go late, it will be gone, so you can open a restaurant, but it should be economical and affordable for students. In addition, I can have some barbecues or something in the evening. I have considered doing this, but I can't help it when I am away from home. In addition, you can choose internet cafes, logistics and the like, hehe, good luck!
