Generally speaking, the most common birthday is to invite friends to a restaurant for dinner, and then go to KTV to sing a song. The consumption of hotels and KTV is very high. It costs a lot of money to eat and play casually. Sometimes you still don't enjoy yourself after spending the money.
At this time, you can buy your own food and cook a big meal for this birthday party, which is both economical and decent. This is the way I celebrated my birthday when I was in college. At that time, the living expenses for one month were not much. If I go to a restaurant for a meal for half a month, my living expenses will be gone. So I found a diy around the school, went to the supermarket to buy some dishes, which were very cheap, and made my own birthday meal.
Because I can cook, I spent some time cooking a table of dishes for them. It is sincere and decent, and there will be no shortage of dishes. If you can't cook, you can invite some female friends who have fun to come and help. I think they are all happy to come and help, because this kind of birthday is very special and can deepen the feelings between friends.
For friends who have already worked, you can invite all your friends home on weekends and then prepare such a table, which will be more warm.
Another way is to go out and have a birthday party. You can choose a place with good scenery around you, and generally don't charge tickets. Let's get together to chat, relax, prepare something delicious, play games while playing, and have an unusual birthday party, which not only saves money, but also is decent.
