The fast-developing society is like a huge gear that rotates continuously, fast, and fast. Under the fast rhythm, people compete fiercely, and even have no time to think too much about what they are doing and why they are doing it. Passively, wrapped forward. Starting from the proposition of "looking for gears", the film interviews the groups who set up stalls in the streets and alleys to make a living, thus extending to the life of the deaf-mute couple, the core object of the film. While showing the life and employment style of the hearing impaired, it conveys a positive attitude towards life. The employment methods of the hearing impaired are relatively limited. The deaf-mute Lin family makes a living by selling wheel cakes at stalls. A small silent stall is not only a picture of their hard work, but also a reflection of the society's concern for the disabled. After half a year's record and follow-up, we can see that even if we communicate in sign language, we can convey sincere feelings, see the orderly warmth and care in front of the silent booth, see that they always have a smile on their faces. Try to convey a friendly signal to the outside world, and see the simple pursuit and optimism of life.
