What does it mean to be born in Tianjin?

How the word "Tianjin" first appeared is related to the great poet Qu Yuan. Qu Yuan's "Li Sao", "Suffering from Tianjin in the morning and suffering from the west in the evening." Get up from tianhan ferry early in the morning and arrive at the west edge at night. Then, is Tianjin mentioned by Qu Yuan a place name, or does it refer to rivers and waters?

We can assume that he refers to place names. At that time, Tianjin was under the jurisdiction of two countries, Beichen belonged to Yan State, Jinnan Jinghai belonged to Qi State, and most areas along the Bohai Sea belonged to Qi State. Qu Yuan worked as a doctor in San Lv, the southern state of Chu, and was sent to the State of Qi to observe the national strength. From Er Ya, Qu Yuan knows that Tianjin is "a place of analyzing wood, between zhe and Han and Jin." He suggested that Qi State visit the end of the sky. At that time, Tianjin had no cities and no sanitation facilities, only many small rivers. So the poet went to Haihe River, a magical land where more than 300 small rivers flow into the sea. Qu Yuan regards it as a starting point and birthplace. It should be said that Qu Yuan first put forward the place name of this area. This trip had a profound influence on Qu Yuan. He returned to Chu and wrote his masterpiece Lisao, from which the name Tianjin appeared.
