《秘密》这部纪录短片将镜头对准了一群老人，这群老人常年在灞桥区半坡立交桥下摆地摊，卖给打零工的农民工们。 本片之所以起名《秘密》，是因为“我”发掘了所有摆摊老人的共同特征。老人们凌晨的摆摊行动，不约而同的都隐瞒子女，（凌晨出来摆摊时，子女还在睡梦中。早晨回去时，也常常不惊动子女），因此它们都有一个秘密基地（用来存放摆地摊的物品）。这种秘密行动的背后，揭示了“时间与生命”的主题，更大程度是对“爱”的诠释。

"Secret" focuses on a group of elderly people who set up stalls under the overpass in Baqiao District and sell to migrant workers. The film is named "secret" because "I" discovered the common features of all the old men who set up the stalls. They set up their stalls in the early morning, and all of them keep from their children. (when they come out to set up the stalls in the early morning, the children are still sleeping. When they return in the morning, they often leave their children alone). So they all have a secret base to store their stalls. Behind such secret actions, the theme of "time and life" is revealed, to a greater extent, the interpretation of "love".
