Lyrics of polite songs Lyrics of polite songs: Composed by Xie Xinzhi and Calvin; Xie Xinzhi finishing: Chen Yingshan woke up in the morning and said good morning, brushed her teeth and washed her face for breakfast, tied her shoelaces with her schoolbag, and gave her parents a goodbye kiss. Please, thank you, sorry, polite children, smile happily, thank you, excuse me. Polite children make people happy. When I was at school, I saw my friends say hello, run and jump, play together and say goodbye before school. Thank you, Teacher Xie, for your hard work all day. Please thank me. Sorry, polite children are smiling, thank you. Excuse me. Polite children make people happy. When I sat down to have dinner, I said please start. Have a nice dinner. Wash dishes and clear the table after dinner. Please thank me. Sorry, polite children are smiling, thank you. Excuse me. A polite child makes people happy when they sleep at night and says good night. The happy day is over. Turn off the lights, close your eyes and give my parents a good night kiss. I am a polite boy. Please thank this polite child. Please smile, thank you, I'm sorry. Polite children make people happy.
