Guess who said "I will search high and low": Qu Yuan.

Qu Yuan (approximately 340 BC - 278 BC), surnamed Mi, family name Qu, given name Ping, courtesy name Yuan[1], also named Zhengze from Yun Dynasty, courtesy name Lingjun, was born in Danyang, Chu State Zigui (now Yichang, Hubei) was a poet and politician of the Chu State during the Warring States Period. Qu Yuan is a descendant of Qu Xia, the son of Xiong Tong, King Wu of Chu. Because he was excluded and slandered by the nobles, he was exiled to northern Han Dynasty and Yuanxiang River Basin. After the Chu State's Yingdu was conquered by the Qin army, he sank into the Miluo River and died for the Chu State.

He is a great patriotic poet in Chinese history, the founder of Chinese romantic literature, the founder and representative writer of "Chu Ci", and pioneered the tradition of "vanilla beauty", known as "The ancestor of Chu Ci", Song Yu, Tang Le and Jing Chai, the famous Ci and Fu writers in Chu State, were all influenced by Qu Yuan. According to legend, the day when Qu Yuan committed suicide by throwing himself into the river was the fifth day of the fifth lunar month, which is the Dragon Boat Festival. The Dragon Boat Festival was originally a festival for the Chinese people to cure diseases and prevent epidemics.

Before the Spring and Autumn Period in the Wuyue area, there was a custom of holding tribal totem sacrifices in the form of dragon boat racing on the fifth day of the fifth lunar month. Later, because Qu Yuan died on this day, it evolved into a traditional festival for the Chinese people to commemorate Qu Yuan. In 1953, on the 2230th anniversary of Qu Yuan's death, the World Peace Council passed a resolution identifying Qu Yuan as one of the four major cultural celebrities in the world commemorated that year.
