What are the idiomatic stories of Jingzhong Zuanguo?

Yue Fei's mother, Mrs. Yao, one of the four wise mothers in ancient times, taught her son to be loyal to the country. As an example of motherhood and a role model for women, she inspired her son to join the military and serve the country in times of national crisis, which has been passed down as a good story and honored by the world as a virtuous mother. When Yue Fei was fifteen or sixteen years old, the Jin invaded from the north, the Song Dynasty was corrupt and incompetent, and the country was at a critical juncture of life and death. Yue Fei joined the army to fight against the Liao. Soon after his father's death, he was discharged from the army and returned to his hometown to observe his filial piety. In 1126, when the Jin soldiers invaded the Central Plains, Yue Fei joined the army again. Before his departure, Mrs. Yao called Yue Fei to her and said, "What do you plan to do now that the country is in trouble?" "Go to the front line to kill the enemy and serve the country with loyalty!" Mrs. Yao listened to her son's answer, "serve the country with loyalty" is exactly what a mother wants for her son. She decided to tattoo these four words on her son's back so that he would always remember them. Yue Fei unzipped his shirt, revealing his thin back, and asked his mother to make the stab. Mrs. Yao asked, "My son, the needle is very painful, are you afraid?" Yue Fei said: "Mother, a small steel needle is nothing, if you are even afraid of needles, how to go to the front line of the war!" Mrs. Yao first wrote words on Yue Fei's back, and then stabbed him with an embroidery needle. After stabbing, Mrs. Yao put vinegar ink on it. From then on, the words "Be loyal to the country" remained on Yue Fei's back forever. Yue Fei was inspired by his mother. After joining the army, Yue Fei was soon promoted to the rank of Bingyilang for his bravery in battle. When Kaifeng, the capital of Song Dynasty, was besieged by the Jin army, Yue Fei went to the rescue with the vice marshal Zong Ze and defeated the Jin army many times, and was appreciated by Zong Ze who praised him for his "wisdom, courage and talent, which could not be surpassed by the ancient good generals", and later became a famous hero of the anti-Jin Dynasty, admired by the people of all times
