Cheng Tianshuang changed his name to Cheng Yumeng in order to disguise himself. This seems to be a perfect disguise, but it exposes his inner sadness. The definition of Yu Meng in Shan Hai Jing is a monster with human form but short wings. Can fly, but can't fly far. Feather lived in the Republic of China, close to the mountain. They stood on the side of the mountain all day, trying to fly farther and farther with their wings, but they always fell and suffered a fiasco.

At the beginning of the film, Cheng Yumeng made a sharp comment, which captured a successful person. However, this is just a successful disguise. The truth is terrible when the mask is lifted.

She is the author of a magazine food column. She made all the preparations for a business trip to Italy. However, her plan failed. She went to Nepal by mistake, where she met RoyceWong, a rich second generation, and Li Meiling, a lovelorn woman.

Cheng Yumeng, who has just arrived in Nepal, has no joy at all. She is still pretending in front of everyone. When she talked with Li Meiling, she was full of lies and talked about European countries, which made Li Meiling always admire her. It seems that this can satisfy her vanity. Guided by the tour guide, they came to the yoga master. This is a kind of spiritual practice, but the appearance of RoyceWong changed his taste. He took the master's hand and kept spitting, and all the speechless people were dissuaded.

Cheng Yumeng, who parted ways, lives alone. Suddenly, the power went out and it was dark around her. She went out with a flashlight, frightened by the frogs around her, and ran to other houses to knock on the window, but no one answered. Her inner fear tore off her disguise and exposed her vulnerability. She squatted hysterically in the corner. She said, please, I'm afraid of the dark. Listen to me if you don't talk. I paid all the money my parents gave me. My parents gave me money to treat me to their big meal.
