In 1974, Zhu Meihua, a female intellectual, was on the side of Xishuangbanna, and her fate ushered in a sudden change. This story takes place on a muddy night after the rain, Zhu Meihua is tired from work and has a dull pain in her stomach. She tried to endure, but the pain in her body forced her to walk to the toilet 80 meters away.
Labor life in this tropical rainforest is full of hardships, and it is undoubtedly a test for Zhu Meihua, the eldest lady from Shanghai. She used to be a delicate girl in Shanghai Xinhui Middle School, but she did not hesitate to respond to the call of the country's border movement and came to Xishuangbanna.
In this difficult land, she and her companions worked together to build a thatched dormitory, which she persevered day in and day out, despite the inconvenience of the distance to the toilets. However, the rain on this day made Zhu Meihua's hardship even more difficult.
At night, her stomach suddenly began to ache, but the toilet was too far away, the night was dark, and the road was muddy and difficult to walk. She tried to wake up her roommate Liu Guihua, but got a confused answer, Liu Guihua said that she had already been. Alone, Zhu Meihua had to go to the toilet alone, but never came back.
The next day, her classmates found her shoes and placed them in a corner near the toilet. There was no blood, no traces of a fight, eliminating the possibility of a beast attack. Her disappearance became mysterious, causing great concern from higher authorities.
As time passed, the task force launched a search, but no trace of Zhu Meihua was found. The anxiety of their families and classmates is heating up, and their bitter wait eventually turns into endless regrets.
The direction of things has become confusing, and the suspect who first surfaced was Zhu Meihua's ex-boyfriend Zhu Weimin. The two were emotionally entangled, and Zhu Weimin once wrote the words "burning Zhu Meihua" because of revenge. However, there was a lack of substantial evidence, and Zhu Weimin was released.
Two years later, Jiang Jinshan, the instructor of Zhu Meihua's company, was caught in the scandal of his niece. This made the task force suspicious of him. Jiang Jinshan finally admitted that he had a crush on Zhu Meihua, but once again changed his story and said that he was forced to confess. Lacking conclusive evidence, he was convicted and imprisoned.
Zhu Meihua's disappearance case remains unsolved, and forty years later, her companions are old, and she is still smiling like a flower at the age of 21. The parents' waiting and hope for their daughter are engraved in their hearts like a song that never ends.
