Lu Jun is the youngest son of Lu Yanque of the Lu Mansion in Chang'an. Lu Yanque only had a young son when he was middle-aged. He was also a legitimate child, so he had to pamper his son. The ancestor of the family was very fond of his grandson, so he was used to Lu Jun walking around the house.
Lu Jun has an elder brother, Lu Yi, Lu Yanque's eldest son. Even the emperor praises Lu Yi for his upright life, good conduct, and achievements in both civil and military affairs. However, he is unlucky to have a younger brother like Lu Jun who gets into trouble. Lu Yi takes care of all the big and small mistakes for him. They are brothers, but more like father and son. Lu Jun is less than two years older than Lu Yi's son Lu Han. He spends all day playing around with his nephew. Lu Yi gets a headache when she sees the two boys getting together.
Lu Yanque was a rough man. He disliked scholars the most in his life, but he didn't know that his younger son wanted to study. He was so angry that he couldn't do anything about it. He turned a blind eye and agreed to the "sour and smelly" hobby of his "unsatisfactory" son. However, he often said a few words, which caused wars between father and son, which never stopped.
Lu Yi said that she was very tired, her father couldn't afford to offend her, and her younger brother couldn't afford to scold her. Her son was following his uncle, and his younger brother was messing around all day long.
