I later studied in Beijing Yibo Studio, where the teachers were very responsible. I draw until after midnight at night, which is very strict. Every student's paintings will be graded and commented one by one. But also for each student's weakness, specially explained.
Anyway, I have been to several studios, and it is the most responsible one I have ever contacted, with high cost performance. Please recommend it.
The studio is located in Unit11kloc-0/unit 39, North Zone 2, Tiantongyuan. Tuition is not expensive, and the cost performance is quite high.
