What's the story between Su Dongpo and Huang Tingjian?

Su Dongpo and Huang Tingjian were both great writers and calligraphers in the Northern Song Dynasty. Huang Tingjian graduated from Su Dongpo's school and is one of the "Four Bachelor of Su Men". They are good friends, and often sing poems, write lyrics, play chess and write couplets together. Once, they played Go under a big pine tree. Suddenly, a pine nut landed on the chessboard. Huang Tingjian enjoyed this scene and took the first film:

Panasonic go, pine nuts fall with the chess pieces every time;

Su Dongpo looked around and saw an old man sitting under a willow tree beside a small river in the distance. He blurted out the bottom allied:

Fishing by the willow is often accompanied by a long fishing line.

Another time, they went out to play, and in the evening, they came to a river, just as the sunset reflected the heart of the river and the golden waves rippled. Huang Tingjian a word way:

The sunset glow reflects the water, and fishermen compete to sing river red;

The word "Manjianghong" here has two meanings, which is not only the scenery in front of us, but also the name of the inscription. There is no doubt that the requirements for downlink should also meet this condition. Su Dongpo thought for a moment, then to the bottom allied way:

Snowflakes are flying in the air, and farmers are playing cosmic music together.

Su Dongpo used "snow" to describe "sunset glow", both of which are scenery; Similarly, the inscription "Man Jiang Hong" with "Pu Tian Le" is neat and smooth, which makes Huang Tingjian claim to be wonderful.
