I learned the word "canvas is safe" from student Wei Xinye.

? Yesterday, among the questions that students were asked to do, there was a comprehensive research topic:

On the occasion of the seventieth anniversary of the National Day, the school will hold a singing contest of "Singing the Motherland", and the students' union will select the host of the singing contest in the whole school. Please draft a slogan for the singing contest.

? The slogan that Wei Xinye, a student in Class Four, intends to write is beyond my expectation:

Celebrating the 70th anniversary of the founding of People's Republic of China (PRC), the canvas is safe and sound;

Singing rivers and mountains for ten thousand years, standing still.

? No matter what this sentence is, it is the first time that I have encountered the word "canvas is safe". I don't know what it means, let alone whether the word is used properly.

? Let Wei Xinye explain to you what "canvas is safe" means. He unhurriedly moved out of the recently studied poems by Li Bai, Du Fu and Bai Juyi. It turns out that this word comes from Li Bai's poem Autumn in Jingmen. The original poem is as follows:

Xiaqiu Jingmen

Tang Dynasty: Li Bai

In autumn, first frost was in Jingmen, and the leaves were scattered all over the place. Because of the mountains and the wide river, the autumn wind also sent me away, which made my journey safe.

This time I went out, not to eat delicious food, but to visit famous mountains and rivers, so the place I want to go is in the mountains.

? I looked up Baidu Encyclopedia and explained it like this:

The second sentence, "The autumn wind hangs on the canvas unharmed", inherits the word "Jiang" in the previous sentence, and secretly points the word "Xia" in the title. Gu Kaizhi, a great painter in the Eastern Jin Dynasty, asked for leave to join the army of the shogunate in Yin Zhongkan, Jingzhou. Zhong Kan specially lent him the cloth sail. On the way to a strong wind, Gu Kaizhi wrote to Yin Zhongkan, saying, "Be safe for pedestrians and sail." Here, the allusion of "canvas is safe" is borrowed, which not only means that the poet's journey is safe, but also means smooth sailing and helping others. This autumn wind scene in "The Original Boat is 300 Li" vividly shows the poet's unparalleled optimism and relief.

From this perspective, this child is the right word.

I have seen Teacher Yi Yan Tang, which is the teacher who teaches us Yi Yan Tang, so by analogy, Wei Xinye is my Teacher Yi Yan Tang. Think of the sentence in Han Yu's Shi Shuo: "Disciples don't have to be inferior to teachers, and teachers don't have to be superior to disciples." Perhaps, we really want to start the era of learning from children, teachers and students learn together.
