What is the structure of lifelong events?

Lifelong events are unique in structure. Although the length of the whole play is short, the plot is highly concentrated. The beginning is straightforward, pointing out lifelong events, with ups and downs in the middle and a meaningful and thought-provoking ending. The whole play begins with Mrs. Tian asking the blind to tell her fortune, and the first sentence at the beginning explains "a lifelong event". Then, through Mrs. Tian's letter and the fortune teller's "telling the truth according to the order", she not only explained the plot before the curtain, but also set the first obstacle to free marriage-feudal superstition. After Tian Yamei appeared, contradictions and conflicts quickly unfolded. The superstitious Mrs. Tian opposed her daughter's marriage. Tian Yamei argued, but seeing that she could not succeed, she had to rely on her enlightened father. Whether Mr. Tian supports his daughter or Mrs. Tian is a suspense. At the same time, Tian Yamei asked Mary, the maid, to send a letter to Mr. Chen, paving the way for Tian Yamei to leave with Mr. Chen in the future. After Mr. Tian came to power, he criticized Mrs. Tian for believing in clay sculptures and blindly telling fortune. Mrs. Tian is anxious and angry, but Tian Yamei seems to have met a savior. However, at this moment, the plot suddenly changed. Although Mr. Tian is not superstitious, he believes in "China customs and rules" and "ancestral temple rules". He also quoted classics and opposed his daughter's marriage to Mr. Chen, and his attitude was more determined. From Tian Yamei's savior to the second obstacle to her pursuit of free marriage. In this way, the contradiction has intensified to the point where it has not been alleviated. As a woman in a new era, Tian Yamei did not compromise when she encountered many obstacles. Her excuses and entreaties were useless, so she resolutely stood up and ran away from home. When the conflict reached its climax, there was an unexpected but satisfactory ending. Generally speaking, lifelong events have a subtle structure, with a beginning and an end, and distinct levels. The suspense, sharp turn, contrast, ambush and echo used in the play are also just right.
