What we are seeing now are the buildings of the Tang Dynasty and the Five Dynasties. At this point, the wood structure has basically matured. What we are seeing now is the East Hall of Beixing Temple. The East Hall is the main hall of Bei Gong Temple, occupying the highest position in the last courtyard of the whole temple. The temple was built in the 11th year of Tang Dynasty (AD 857). On the original site of Maitreya Buddha Pavilion, it was presided over by female disciple Ning Shizi and monk Cheng Cheng. The East Hall is seven rooms wide and four rooms deep. In the words of Mr. Liang Sicheng, this temple is a typical Tang Dynasty building, which is "a big arch and a far eaves". According to the measurement, the cross section of the bucket arch is 2 10×300 cm, which is ten times that of the bucket arch in the late Qing Dynasty. The eaves of the temple reached 3.96 meters, which was not found in the wooden structure buildings after the Song Dynasty.
At the same time, the top of the main hall frame adopts a triangular herringbone frame. The service time of this beam-frame structure ranks first among the existing wood structures in China. In the early 1980s, people found the news about people visiting Beidou Temple in the Tang Dynasty behind the door of the main hall. It can be seen that this gate should be a relic of the Tang Dynasty. It can be inferred that this door panel with a history of over 100 years is the oldest wooden door in China. In addition, the roof of the main hall is relatively flat.
