简介：The backyard is much smaller and messier, with a loess floor, an old locust tree with lush branches and leaves in the corner, and a well covered with a stone cover under the locust tree.

Sitting next to it seems to be facing the open refrigerator door, so the master and apprentice often enjoy the coolness here and chat.
