Haihe water: It has been flowing for more than six hundred years. I have seen the Tang family's ships sailing out to sea, and I have also seen the Tang family's ships never return. This is a Tianjin version of "The Big House", telling the story of the Tang family's ups and downs over nine generations and three hundred years from when they took root in Jingu during the Kangxi period, from 1670 to the departure of the last witness in 2007. With "boat" as the soul, "water" as the pulse, diligence as the foundation, and loyalty as the legacy. It describes the various scenes of Tianjin Wei's city life, the clouds at the wharf, the glory of the imperial examination, the smoke of Nanyang, and the tenacity of an ordinary person in the torrent of the New China era.
