Brief introduction and detailed information about them and them

Plot summary

Dalin and Xiaolin are twin brothers, and Fangfang and Yuanyuan are twin sisters. Xiao Lin works as a salesperson in a food store, and Yuanyuan works in an electrical factory. Both are smart but lack enthusiasm for work. Dalin is a purchaser at a research institute, and Fang Fang is an experimenter in a chemical plant. Both of them have a very serious work attitude. Xiao Lin was introduced to Yuanyuan by his cousin. Dalin got acquainted with Fang Fang, who was responsible for trial production of the adhesive, in order to purchase the high-strength adhesive that was urgently needed in the institute. Xiao Lin and Yuanyuan went on a date. Dalin and his parents secretly went to see them, but there was a misunderstanding. Dalin mistook Yuanyuan for Fangfang, and Yuanyuan mistook Dalin for Xiao Lin, which led to a series of jokes. Fang Fang's experiment needed "Resin No. 8". Dalin ran around to help her find it, but he was admitted to the hospital due to an attack of appendicitis during the process. Later, Dalin learned that a factory in Changzhou had "No. 8 resin", so he exchanged clothes with Xiaolin and sneaked out of the hospital to look for it, which moved Fang Fang very much. Xiao Lin came to Fang Fang to take samples for his brother. He accidentally knocked over the adhesive and it was firmly stuck, which inadvertently proved the success of the experiment. Dalin and Fang Fang firmly established a sincere love at work. Xiao Lin and Yuanyuan also realized their mistakes and actively devoted themselves to their work.
