Judging from the curriculum standards of various disciplines, the expression of core literacy is basically the same. "Chinese Curriculum Standard for Compulsory Education (2022 Edition)" clearly points out: "Core literacy is the correct values, necessary characters and key abilities gradually formed by students through subject learning, and it is the concentrated embodiment of educational value."

"The core literacy of Chinese course training in compulsory education is accumulated and constructed by students in active Chinese practice activities and displayed in real language use situations. It is a comprehensive embodiment of cultural self-confidence and language use, thinking ability and aesthetic creation."

From the above statement, the core literacy of Chinese course training in compulsory education includes four aspects: cultural self-confidence, language use, thinking ability and aesthetic creation. Among these four aspects, "cultural self-confidence" has a higher status and plays a leading and guiding role in the other three aspects.

Reading Mulan's poems, we read the story that Mulan joined the army as her father. Before Collection for Grandpa from now on, we saw Mulan's bold decision to be a city pommel horse. Because when Mulan was weaving at home, all we heard was Mulan's "chirp" sigh.

Why "I can't smell the loom, but I can smell the woman's sigh"? Because there is a huge contradiction here-the military post "has the name of grandfather" and "grandfather has no eldest son and Mulan has no eldest brother". In order to solve the problem for her father, Mulan made up her mind, "I am willing to make a pommel horse for this city, and I will sign it for you from now on."

In the process of "recruiting for grandpa", Mulan twice "didn't hear grandpa and mom calling for female voices", but "heard the Yellow River splashing" and "heard Yanshan Hu riding".

It shows that Mulan made the decision for grandpa and family, and now it is not only for grandpa and family, but also for the country. This is the most important thing. When she returned from the war, facing the reward from the Emperor of Heaven, Mulan directly said, "Don't worry, I am willing to send my son back to his hometown.".

Here, we can see that Mulan joined the army as her father not for "honor" or "reward", but for her family and country. Reading Mulan's classic poem written by Yuefu, we should read the classic and profound theme, the feelings of home and country in the poem, and Mulan's heroism.
