Why is warm tea learning free?

Warm tea study provides quality service for customers and attracts customers to patronize for free.

Warm tea study has two floors, one is a coffee and beverage area and a book reading area, and stationery is also sold. Some seats in good positions need to be drunk before they can be used (marked on the table), and some tables and chairs can be used for free. Steps and mats with logs in many areas are also very suitable for quiet reading.
