Although Lu Jingshu was from the side branch of the Lu family, she had a lot of say in the Lu family. Not only was she married into the Hua family, but her father and brother also occupied a very high position in the Lu family.
The main branch of the Lu family had declined. Although they still occupied the position of clan head, their control over the various branches of the Lu family had weakened considerably.
Lu Jingshu's family was only an outstanding branch out of many and enjoyed a relatively good relationship with the main branch. Under such circumstances, the main branch of the Lu family would not offend her. Therefore, although Eldest Madam Lu was unwilling, she still brought Lu Deyin and her brother along.
