First, let's take time as an example. Is it day or night? A few hours or a night? If it's daytime, you can climb the mountain in Beishan when Hunchun is not cold, and sit in a coffee shop (Good morning Dole, including purport), all of which are better. If it's night, why not go to the bar (Scala, kaos)? If it involves staying overnight, you can consider villas (there are too many villas, I can't remember the specific names, but some can stay overnight, and now there are game to eat).
Second, personnel. Is it three people, five people, not a dozen, or more? Few people can go to coffee shops or teahouses, and many people can eat skewers. At present, there is a table with a dozen or twenty people sitting together in Hunchun (border barbecue on the edge of Yushan or Jinghe Bridge), which is particularly large. You don't have to bake it yourself, and the atmosphere will be good.
Third, the question of money. This question is very realistic, but I have to say it. More money and less money directly affect the arrangement of activities.
I wasted too much time here. In fact, I always get together with my classmates. It is difficult to get together once, and it is not easy for my classmates to get together once. Hunchun is so big that there is not much choice. But in any case, the improvement of classmates' feelings is the most important thing. Have fun!
