I have been to Lao Fengxiang's counter before. Generally, it is after-sale, and the maintenance is free in a short time, but it takes a long time and is seriously damaged. It is estimated that some labor costs will be charged. You can ask clearly when buying products.

Lao Fengxiang has cooperated with short-term trust platforms before, pushing and sending live and dynamic information and chatting with their employees. General brand products, products and after-sales service will not be too bad.
