How did Bing Xin get his pen name? On the origin of Bing Xin's pen name

1, pen name Bing Xin, is taken from the poem "Lotus Inn and Xin Jian Parting" written by Wang Changling in the Tang Dynasty: "Friends and relatives in Luoyang are like asking each other, and there is a piece of Bing Xin in the jade pot". 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.

2. The whole poem of "Furong Inn and Xinjian Bie": It is cold and rainy at night, seeing off the guests in Chushan. Friends, if my friends in Luoyang invite me; Just say I'm still Bing Xin Okho, and stick to my faith!

This poem was written in the first year of Tianbao (AD 742), when Wang Changling was Jiangning Cheng. Xin gradually is a friend of Wang Changling. This time, he plans to cross the river from Runzhou, pass through Yangzhou and go north to Luoyang. Wang Changling may accompany him from Jiangning to Runzhou, and then break up here. This poem was written for the parting river.
