Beijing adult calligraphy training class

I want to attend a calligraphy training class soon. Requirements: 1. Basic classes, small classes, large classes, or personal classes organized by professional teachers in calligraphy. 2. The best place to attend classes was in the northwest area of Haidian District or other areas where the subway was convenient. 3. It would be best if the class time was on weekends or on weekdays. Didn't the first line say," I want to attend a calligraphy training class in the near future?" My personal situation and basic requirements for the training class were written down. If you have any resources in this area, please let me know. Thank you.
