At half past eight, I often go to the mainland. The conditions are good, but there are many people on weekends. I'll arrive at about 7: 30, but it won't be more than 7: 50 (unless I cut in line). Now I don't charge for my own food ... but I'd better go to the first floor, where there is catering service for readers.
If there are no seats in the study room, you can go to the reading room on the left side of the lobby on the second floor to study for yourself. It seems that only the inner room is left unattended. You can teach yourself.
It's hard to fight unarmed. I hope to adopt it.
