In this picture, the gray background color is selected. First, a winding path is drawn, and then the painting is based on the path home. The path is getting farther away, thinner and blurred.

At the end of the path, draw the outline of the building. Because of myopia, the first building can be painted bigger. The second building is smaller because of its farsightedness.

Draw a row of large windows on the first building and a row of smaller windows on the right. Choose black. In the second building, the windows are smaller than those in the first building.

On the right side of the road, draw irregular figures in white to form the appearance of unmelted snow drifts in winter.

Draw thick branches and trunks on the snowdrift. Because of the cold winter, all the leaves have fallen and the branches are bare. You can draw more small trees or shrubs if necessary.

Finally, draw a silhouette of a person on the path. The outline of a person is black. Outline the evening or evening time. The road home is complete.

On the way home, I can always smell something burnt. When I look carefully, it turns out that some small vendors on the roadside are baking unsanitary kebabs. When the wind blows, they are covered with a lot of dust. Coupled with those dirty hands, people feel sick, but some greedy students don't care so much. They only know how to ask their parents for money and buy some junk food.

But who will think about how many bacteria those things contain, which will affect their health and endanger their lives, and they will not throw their bamboo sticks and disposable lunch boxes into the garbage bin after eating, but just throw them on the road. Those small bamboo sticks and disposable lunch boxes that were abandoned on the road rolled back and forth, as if begging people to send themselves home, so as not to let them "wander" any longer.
