Why does grandma say there is a laurel tree on the moon in the article "Moon Marks"?

Because of the story of Wu Gang cutting Guangxi.

Legend has it that WU GANG's wife had an affair with Sun Boling, the grandson of Emperor Yan. WU GANG killed Boling in a rage, angered the Sun God of Emperor Yan, and was sent to the moon to cut down immortal trees. However, laurel and cuttings hit it off. Every time WU GANG cuts an axe, the branches and leaves cut by the axe will grow back on the tree. After so long, WU GANG still failed to cut down the laurel tree.

Feeling guilty, WU GANG's wife ordered her three sons to become toads, rabbits and snakes and fly to the moon to accompany WU GANG. In order to help his father cut down the osmanthus tree as soon as possible, Yutu kept mashing the cut branches and leaves.

Extended data:

The moon in Moon Marks symbolizes all beautiful things. The author implicitly tells people that bright and beautiful things can only be obtained by hard pursuit. These works show readers the exquisite pictures of jathyapple painted by children in mountain villages following the path of the moon during the Mid-Autumn Festival, and show the mysterious and generous character of Mingyue.

The composition begins with "We children, everything feels fresh ……", and then describes the children's "full moon" and "full moon" in detail. The author not only vividly depicts the beauty of moonlight, but also writes about children's love for the moon and their naive and curious personality, which laid the foundation for the later "Searching for the Moon".

They followed the trail of the moon to the yard, and there was a dispute about who owned the moon, describing the children's longing for the moon, thus sublimating the thought of prose to a new realm.

As grandma came out to pour wine, it proved that the moon belongs to everyone. Then they found the moon in the yard, outside the yard, on the river boat, in the upper and lower bays of the river, in the eyes of their companions, and suddenly realized: "There are so many moons: as long as you like, it is there."

It shows the children's persistent pursuit of the moon and deepens the theme again. Finally, their curiosity and love of beauty were satisfied and they went to sleep sweetly.
