The film conveys the theme of “love” through the life story of a blind-deaf couple. Facing all kinds of dilemma, the couple maintain each other between light and darkness.

The background of this documentary is the Sign Language Corner of the West Lake Three Parks,which is the most “central” and “marginal” corner of Hangzhou.Every Friday morning, deaf people from all over Zhejiang Province gather here. Among them,  Sang Lianying from Deqing County is a blind-deaf person, and her husband is also deaf. The couple came to Hangzhou for medical treatment.After arriving at the hospital, the doctor informed the wife that her left eye was completely blind, so they returned to Deqing County , waiting for the only remaining hope of surgery on her right eye……

As the oldest way of communication, sign language may be the common language used by humans before the collapse of the Babel Tower .With the rapid development of Hangzhou, someone is doomed to be left behind. In this surging long river of time, the documentary will be the last words written for time.
