In the play, Nobita is a coward. At first he didn't encounter any difficulties, but he escaped. He always feels that he can't do anything well. So he can only go to Doraemon after being bullied by Pang Hu, and he will be taught some truth after Doraemon helps Daxiong get justice. Because of his personality, Doraemon can only teach him not to give up when facing things and difficulties. When Pang Hu is bullied, the best way for Doraemon is to let him face it. Although it is difficult to avoid bullying in the face of Pang Hu, it may be the best way for a person to grow up.
Unlike when we have the Internet now, Nobita's circle of friends is very narrow. In addition to the students in the class, only Pang Hu grew up with them. If Nobita chooses not to play with Pang Hu, no matter how many friends he will lose, the kind of harmonious friendship Nobita hopes is impossible because he has no friends. Although Pang Hu has been bullying Daxiong, and sometimes even done a lot of excessive things, Daxiong does have too few friends, and he will not choose to leave because he always wants to blend in with friends. Because he feels great pressure, being with friends will make him feel valuable. Being recognized by his friends is not only for Nobita, but also for our childhood.
Although Pang Hu often bullies Nobita, when the real Nobita needs it, Pang Hu will stand up and protect Nobita. If Daxiong wants to get on well with the people around him because he has no friends, so does Pang Hu's heart, because he is not good in all aspects and sometimes bullies other children, but he still wants to have companions to play with. Although I know that Daxiong's baseball skills are poor, I still want to go to Daxiong, perhaps because I can't find enough people, but the reason why I can think of playing baseball with Daxiong may be because Pang Hu needs Daxiong as a good friend in his heart. So I think this is because of Nobita's personality, Nobita's friends and Pang Hu's attitude towards Nobita.
