I and my sister had studied 中文 at LTL 成都 for 5 weeks and had a great time! I came to 成都 from having close to zero Chinese knowledge to passing HSK 2 on the last day!
I had an amazing time learning with my Chinese teacher, Ying 老师. She was very energetic and caring. She always tried her best to answer and clarify whenever I had questions relating to Chinese grammar, vocabulary, etc. She is very knowlegable about Chengdu and knows lots about tourist locations, restaurants, etc.
LTL Chengdu is located at a very convenient location, only a few minutes of walking distance to IFS, Chengdu's city center. The building which LTL Chengdu is located at is also really nice, it has a few coffee shops, study areas, a gym and also located near several milktea shops, restaurants and convenice stores.
Every Thursday evening, there will be a social gathering event happening at LTL Chendu. It's a great time to socialize with other Chinese learners and teachers. During my time at LTL Chengdu, there weren't a lot of events to participate in. But I got to meet with other Chinese learners from all around the world with varying Chinese skill levels. It was very interesting to know each others' Chinese learning experiences and their own native language, culture.
Overall, LTL Chengdu is a great place to learn Chinese, to meet with other international learners and has lots of flexibility for you to explore Chengdu.
