Introduction to Ma Chao's Tomb: Ma Chao's tomb is rectangular in shape. It was first built in the third year of Zhangwu (223). It was originally a Han-made overturned bucket style. The terrain is flat and surrounded by farmland. The circumference of the tomb base is 56 meters and the height is 3 meters. In front of the tomb A stone tablet was erected to read the tomb of Ma Gongchao, the general who conquered the west of Han Dynasty. There is a "watch monument" beside the road in front of the tomb. According to the investigation, the original building of the cemetery was a long corridor from the "Wangbei" temple to the tomb. After several vicissitudes, the tomb was surrounded by towering pines and cypresses, and the pavilions were connected. The solemn and spectacular scene of each tomb no longer exists. When the Han Hui Canal was being built in the 24th year of the Republic of China (1935), an iron knife was found outside the corridor of Ma Chao's tomb. It was feared that there was a hidden weapon inside the tomb and it was closed again.
