Xiaoyu has asthma, so her family only has this medicine, which is when her mother suspects that she is insane. Because she saw Qingyi and Ye Xianglun, she mistakenly thought that Ye Xianglun felt the same way, which led to asthma.
Son, asthma is certainly a disease, which has a lot to do with mood. So every time Xiaoyu sees Ye Xianglun and Qingyi together, she will go back to 20 years ago.
(2) About time and space:
There are three time and space in the plot. The first two time and space are Xiao Yu's love with Xiang Lun, often in the classroom and piano room. The third time and space is when Jay Chou finally plays the secret and the piano room is torn down.
(3) twenty years, two time and space:
As for these twenty years, they exist in different time and space, namely 1979 before Xiaoyu discovered the secret, 1979 and 1999. However, the behavior of characters is reflected in three time and space at the same time, and the same result is produced in another time and space. In any time and space where they have existed, they have influenced and changed the fate of themselves and the people around them. Because these time and space exist at the same time, the behavior of characters will produce inexplicable mistakes or strange events in both time and space. For example, the dialogue between Qingyi and Xiaoyu while playing the piano is just a single dialogue in another time and space, because Ye Xianglun was not the first person to see Xiaoyu after crossing this time and space, so he watched it in this time and space. Xiaoyu's words written with correction fluid are also reflected in another time and space because of the relationship between time and space.
Because of her excellent grades and unique temperament, Xiaoyu was rejected, misunderstood and bullied by the opposite sex in this time and space. No one wants to believe her, and so does her mother (maybe there were signs of madness earlier), so she tried to play Secret on the piano alone and travel through time and space. Twenty years later, she met Ye Xianglun and verified the records on the piano. She told her teacher, Ye Xianglun's father.
Because of misunderstanding, Xiaoyu returned to the previous time and space and even disappeared 15 days. In this 15 day, Xiaoyu may have come back, but the first thing I saw was not Ye Xianglun, but Yong. That's why Dayong said, "I thought you would bounce back."
(4) Dayong, Xiaoyu's mother, Shannon's father:
Dayong, the janitor, was stupid for eavesdropping on secrets 20 years ago. Xiaoyu's mother lost her daughter because she didn't trust her, but later she knew her mistake because of the statue Xiaoyu painted. Xiang Lun's father told Ye Xianglun about Xiaoyu, saw Xiaoyu's signature on the piano score, discovered the secret, and their fate was changed. Twenty years ago, Xiaoyu's mother was lonely and crazy, brave and timid, so Xiang Lun told Ye Xianglun about Xiaoyu.
⑤ Results:
Xiaoyu misunderstood Ye Xianglun and Qingyi on 1979, causing asthma. Written with correction fluid before he died, Ye Xianglun saw it because the last one was not finished. Xiang Lun couldn't help but find out, found the secret, and asked his father for proof and then played the secret.
And the ending is the same, because the fate of each character in the same time and space is interspersed in time and space, and his own behavior affects the fate of the same character in two time and space. So, there are several explanations about the ending. One is that the rain died in 1979, which is a tragedy; Before 1979 Xiaoyu discovered the secret, they reunited in time and space, but it was too early! Xiao Yu doesn't know Xiang Lun; 1999 middle-aged in light rain, Shannon disappeared.
⑥ About light rain:
Xiaoyu died or not because there is a reasonable explanation for the relationship between time and space. Xiaoyu disappeared in the space-time of 1979, and Xiaoyu may have died in this space-time.
When Xiaoyu appeared at Ye Xianglun's graduation ceremony, her hair was long, but it showed that she was in another time and space because of Qin. There is a saying that Ye Xianglun went to Xiaoyu's home and led Ye Xianglun to Xiaoyu's home, that is, Xiaoyu's middle age, that is, Xiaoyu 20 years later, that is, 1999 middle-aged Xiaoyu.
Xiaoyu went to another time and space. Ye Xianglun also played the secret before the classroom was demolished, and returned to the earlier time and space before 1979 discovered the secret, that is, the time and space where Xiaoyu existed. But Xiaoyu didn't know Ye Xianglun at that time, so he would be polite when he saw it. Because the piano was destroyed, Ye Xianglun could only stay in that time and space forever.
Of course, since then, all history has changed, which is why Ye Xianglun was left in graduation photo.
Xiaoyu may live happily with Ye Xianglun in the time and space before 1979 discovered the secret.
Look again, I should understand. I have seen this many times, and then the teacher mentioned the concept of time and space when chatting with us in a class, but it was also very vague. I don't know how many times I watched it before I understood it. At first I thought I understood, but there were many problems that could not be reasonably explained.
Give me extra points. I wrote for a long time and didn't copy at all. Absolutely original!
