Shen Yan, twenty-eight years old, is the third generation descendant of the Shen family tea shop. My grandfather was an old river worker who dredged the Bianhe River with Zhou Shizong, and my father saved the family business by selling tea through the canal. Shen Yan grew up in a tea shop since he was a child. He was used to hearing the chatter of merchants from the north and south, and he also remembered the hydrological proverbs spoken by Uncle Zhou and others. He has a calm personality and doesn't like to work hard. His tea shop business is gradually declining, but he always adheres to his grandfather's rule that "tea must be sold in a manner worthy of one's conscience." When the city clerk came to seal the shop, he had to step out of the tea shop and step into the wind and waves of the Bian River.
