I didn't see a word from the fruit thief. The last sentence is: the old fruit tree in front of the door is ripe. This poem refers to an old child who misses his childhood. Fruit trees refer to edible trees, perennial plants and their rhizomes that can provide edible fruits and seeds. Such as apple trees, pear trees, citrus trees, apricot trees and peach trees. The source "The Biography of Yu Chungong in the Later Han Dynasty": "There are fruit trees in Shan Ye, and some people may invade and steal them, so they need help to collect them." Yang Shuo's "Penglai Wonderland": "In winter, the north wind blows and the fruit seedlings freeze to death."
