Give this pen name in this poem to young readers. What is this poem?

Since Bing Xin published her works under a pseudonym, she has won numerous honors, and even her real name, Xie Wanying, has been eclipsed by her pseudonym. What is the origin of the pen name "Bing Xin"? Put it another way.

(1) 19 19, when Bing Xin published his first novel Two Families, he used "Bing Xin" as his pen name for the first time. According to Bing Xin, "At that time, I didn't want my classmates to know that I wrote the article. Bing Xin's strokes were simple and easy to write, which was consistent with my real name. After I was born, my grandfather asked a fortune teller to tell my fortune. The fortune teller said I should be a man, and I was hit by satellites. He also said that I was short of fire. So my second uncle named me' Wan Ying', and there are two words' fire' on the prefix' English'. "

(2) When Bing Xin lived abroad, she took the meaning of "Friends and relatives in Luoyang are like essays, and a piece of Bing Xin is in the jade pot" in the poem "Parting Xin Jian at Furong Inn" written by Wang Changling in the Tang Dynasty, expressing that she always has a "Bing Xin" who loves her motherland.

So my second uncle named me' Wan Ying', and there are two words' fire' on the prefix' English'. " . "Bing Xin" is taken from the poem of Wang Changling, a poet in the Tang Dynasty: "Friends and relatives in Luoyang are like asking each other, and a piece of Bing Xin is in the jade pot". The reason why she chose "Bing Xin" as the pen name, she explained herself: "First, because the word Bing Xin is simple and easy to write, it means Zi Ying. Secondly, I am too timid to be criticized by others. The word Bing Xin is new. When people see it, they won't think that these two words have anything to do with Xie Wanying. " Therefore, although people call her, she always signs Bing Xin, never surnamed Xie.
