Are Mulan and Yue Fei from the same dynasty?

No, Mulan was a heroine of the Northern Wei Dynasty. She joined the army instead of her father to defeat the invading country. Yue Fei was a famous gold fighter, strategist, strategist, national hero, calligrapher and poet in the Southern Song Dynasty, ranking first among the "Four Generals of Zhongxing" in the Southern Song Dynasty. So it is not a dynasty. Dynasty is the whole ruling period passed down from generation to generation by emperors who established the title of the country, and it is a term that defines a certain political period.
