My family, Emeiyin, and my son are in the same country, sixty miles apart. *** Drinking glass from the rivers and mountains is not against the people. Filling the windows of thousands of houses, but the people in the bitter windows are not aware of themselves. Surrender, return to govern the small country, Hong Zhong chokes and bumps slightly.

The content of the calligraphy work is from Su Shi's "Farewell to Yang Mengrong" of the Song Dynasty:

My family is Emeiyin, and I am from the same country as my son.

Sixty miles apart, we can drink from the glass river.

The country is not against anyone, and it fills the windows of thousands of homes.

But the people in the window of suffering are unwilling to surrender.

When Zi returned to govern a small country, Hong Zhong choked and bumped slightly.

I will stay and wait for you to sit in jade, walking weakly and carrying Feng Feng.

What a talented young man, with the same name as Huang Tong.

I refuse to enter the state capital, and my old friend Yu Laopang.

Be diligent and inquire, cherish the frosty eyebrows.

Why wait for me to return? The cold fermented fermented rice will turn into a spring vat.
