When I came to this library today morning (Saturday)I was originally full of joy as the library looks nice and chill but from 10am to 12:30pm, there was a group of aunts /grandmas (looking ard 50-70years old,7-8ppl) chatting loudly like going to a Chinese teahouse, which made me unable to be quiet at all. I also saw that the people sitting at the front also looked at them, but they looked like no one else was there. It was a very bad experience.
If you want to read a book quietly, it is not recommended to come here.
I am wondering why they don’t book the room or go to the cafe to catch up if they wanna chat.
