Xie Taifu Hanxue gathered in Beijing to discuss the meaning of poetry with his children. Suddenly it snowed suddenly, and the Duke said happily: "What does the white snow look like?" Brother Hu'er said: "Sprinkle salt to make the difference in the air." The brother and daughter said: "It's not like catkins blowing up in the wind." The Duke laughed happily.

Appreciation
This is an eternal story, which reflects the outstanding poetic talent, meticulous observation of things and flexible imagination of the female talent Xie Daoyun.
According to the "Book of Jin·The Biography of Wang Ning's Wife Xie" and "Shishuo Xinyu·Yu", Xie An tasted Neiji during the Hanxue day and lectured on the meaning of essays with his children. Suddenly, the snow suddenly fell, and An Xinran sang. Yun, brother Zilang and brother Daoyungengge (the poem is as above), are happy and happy.
