Therefore, the exotic flowers and fruits of the Quartet have also been introduced and cultivated. During the period of Emperor Wu of the Han Dynasty, the cultivation of fruit trees in Shaanxi entered its peak.

Lisi four... peach ten... Li fifteen... 柰 three... plum Seven...Apricot II", which also records "... 柰 three, white peony, purple 柰 (flower purple), green 柰 (flower green)", that is, small apple or cotton apple.

At present, the sea otters produced in Shenmu, Fugu and other places in Shaanxi have a wide variety and are widely distributed, and some have not yet left the original state.
