The chamber of M4-3 was adapted from that of M4, which was rare in former finds. And its burial objects were also hardly seen in Central China. Poliucun M5 and M6 were in late Northern Zhou and early Sui Dynasties. The bottom of the south and north wall of the patio was battered severely. The tomb structure bore strong characters and some murals were left, enriching the burial archaeological data of the same time.
