I found the language exchange activity at TCML on the Meetup website. I have joined twice now.
The reason why I want to join is because I want to practice my Mandarin, especially my speaking ability. The events offer good opportunities to practice Mandarin, which is very helpful to me.
There are many parts of the meetups that I think are really great. For example, they're well organized. The balance of the number of Taiwanese people and Mandarin learners is good. They're carefully arranged too and everyone is very friendly.
Bubble tea and snacks are provided at the event. I can also meet new people and the place is relaxing.
Because of these advantanges, I would like to recommend it to other people!
