A love story between a librarian and a dentist who overcome misunderstandings to slowly walk into each other’s hearts. The 28-year-old Zeng Li who works as a librarian crosses paths with dentist Ai Jingchu when she had to get her teeth straightened. They experience many things together – a snowy night, hide-and-seek at the orphanage and spending New Year’s aboard a pirate ship. Just as they were about to confess their feelings towards each other, the ‘first love’ that Zeng Li has been waiting for in the past ten years reappears. He is Ai Jingchu’s best friend Liu Yi Cheng who returns to China and begins to pursue Zeng Li.

The TV series “Dust in the World” is an urban emotional drama directed by Xu Hongyu, starring Wu Xuanyi and Bi Wenjun, special starring Zhai Xiaowen, and starring Zhang Baijia, Liu Te and Wan Zilin. The drama is based on Mu Fusheng’s novel of the same name, which tells the love story of Ai Jingchu and Zeng Li.

The 28-year-old librarian Zeng Li met Ai Jingchu, the deputy chief dentist because of his teeth correction. The two experienced together on snowy nights, hide-and-seek in the orphanage, and pirate ship New Year… . Just when the two were about to complain about each other, Zeng Li, who had been waiting for his “first love” for ten years, and Ai Jingchu’s best friend, Yu Yi, returned to China, and pursued Zeng Li fiercely. After reading Zeng Li’s novel “The Story of Ji and Xiao Yuer,” Ai Jingchu misunderstood that the person Zeng Li liked was always Yu Yi, and gave up the confession plan and decided to go to Africa for medical assistance. But because of Yu Yi’s sudden confession, Zeng Li became more clear about his love, and returned to Ai Jingchu without hesitation. The two lovers finally became married.
