What kind of story scene does Yuan's "The Migration Map of Ge Zhichuan" depict?

Located in Zengcheng, Guangdong Province, Luofu Mountain is a combination of Luoshan and Fushan Mountain. It is a good place for Taoism to practice alchemy. It is 3,000 feet high and has 70 stone chambers and 72 streams with birds, Yushu and Zhu Cao on them. The mountains are flat and open. Here is a Yuan painting of Ge Zhichuan's migration, depicting Ge Hong marching with his family in Luofu Mountain. Ge Hong is holding a deer with a feather fan in his hand, and his wife is holding a cow and a son. The other two sons were followed by a servant with a cow, and a servant with a book in front of Ge was sitting at the foot of the mountain to rest. Panoramic composition is taken in the painting, with majestic mountains, overlapping mountains, abundant miscellaneous trees, flowing bridges and extremely quiet. Song Lou Key once wrote a poem:

Mo Yan has less furniture than a car.

The medicine wrapped in the clothes bag has its own surplus grain.

The old woman and her three children,

Xian Weng plays a book alone.

Cattle and sheep tend to build new buildings,

Chickens and dogs have no reason not to love their homes.

The mountains are full of Dan Wells.

I don't know how many times I moved.
