Whose poem is "a piece of ice heart in the jade pot"

"There is a piece of ice heart in the jade pot" is a poem by Wang Changling, a poet in the Tang Dynasty, and it is also a poem in Wang Changling's Lotus Inn and Xin Jian Bie.

The whole poem of "Lotus Inn and Newly Built Farewell" is as follows: Entering Wu on a cold rainy night, seeing guests off in Chushan. Friends, if my friends in Luoyang invite me; Just say I'm still Bing Xin Okho, and stick to my faith!

The cold rain spread all over Wudi River overnight. After seeing you off in the morning, you were left alone in the face of Chushan. When I arrive in Luoyang, if my relatives and friends in Luoyang call me, please tell them that my heart is still as crystal clear and pure as ice in a jade pot!
