If there are many people, you should press the number, such as holidays and so on. If you want to occupy a good position on holidays, it is a big house. You must go early and get there at about 8 o'clock in the morning. If you go late, you can only take a cabin. In fact, most people just went for one morning. At one or two o'clock in the afternoon, there are already many empty seats in the big house, and there is no need to get the number. However, if someone with a number comes, you still have to give up your seat. There are many people in the morning. Now you don't need a self-study card, it's free. It's quite quiet. There is also a power supply. If you read a book, you can charge it by the way or take a notebook with you.
