At the age of 17, Liu Dong began working at a furniture factory in Beijing, where he learned skills such as carving and the restoration of ancient artifacts. Later, he established the Mujushanfang Restoration Studio, specializing in the ancient artifact restoration and ancient architectural components.

Since 2008, Liu Dong has been collecting antiques from regions such as Shanxi Province. His collection is divided into four main categories: tables, seats, cabinets, and wood carvings, with the largest number of items being incense tables. In an interview, he explained that the earlier pieces in his collection are made from pine wood, while furniture from the Ming and Qing dynasties is mostly made from elm wood, locust wood, walnut wood, poplar wood. Liu Dong hopes to one day turn these collections into an exhibition, allowing more young people to take an interest in and appreciate them.
