Zhaojun’s Resent·Plum Blossoms

The Tao is that flowers come at the end of spring, the Tao is that snow comes with a different fragrance. There is a leaning branch outside the bamboo, a wild man's house.

The deserted bamboo fence huts, the rich and noble jade halls and pavilions. Planted differently in both places, it generally blooms.
