There are two unique buildings in Guangdong, one is Kaiping Diaolou and the other is Hakka Enclosed House. The shape of the Hakka Enclosed House is like a bunker and a bird's nest. This kind of building is more in Meizhou. There are several places in Mei Hakka House, the most representative of which is Tai'an Building in Dapu County. This building was built in the 28th year of Qing Emperor Qianlong. It has a history of more than 250 years and can be preserved. Not easy, which also shows the rigor of ancient architecture. Other Hakka enclosures are usually round, while Tai'an is square. The main building materials are stone, wood and brick. Because the outer wall of the building is a stone wall, this building is also called a stone building. Tai'an Building is currently a key cultural relics protection unit. It is also a cultural tourism attraction developed by Dapu County. It is managed by a dedicated person and is well protected in all aspects. Visitors can not only walk on the ground floor, but also climb down the stairs. The second and third floors are panoramic views of God's vision. Taian Building has only one gate for access. If the gate is closed, outsiders cannot enter. The windows of the whole building are very small, which is mainly for the purpose of preventing thieves and preventing problems. Because the wall is thick and strong, the Taian Building has good wind, waterproof and shockproof performance. On the Taian Building, every picture you see in front of you is full of chronology, especially the aging window, as if you are silently telling history. There are more than 200 rooms in the entire Tai'an Building. Currently, only a few old people and children live in it. Most of the young people go out to make a living, or move to a more comfortable modern building.
