The two tombs face each other, and between the two tombs, a large catalpa tree grows on the top of each tomb, which grows and hugs each other for ten days. The two trees bend to meet each other, with their roots intertwined at the bottom and their branches staggered above. There is also a pair of mandarin ducks, perched permanently. In the trees, morning and evening linger, with their necks folded and moaning sadly. People in the Song Dynasty mourned it and called its tree the acacia tree.
