The Qu family was a local aristocratic family in the capital. It could be said that they had been in the capital since their ancestors.
And when they were carrying guns and fighting the Japanese during the war, Elder Qu had the foresight to use all of the Qu family's resources to help them fight the war. Thus, after the war ended, Elder Qu was conferred the title of Founding Minister by the country, he was now a retired chief. At that time, the central government had also arranged for a place for Elder Qu to live in the military compound.
However, Elder Qu was still the head of the Qu family. After the war ended, he still had to take over everything. Therefore, Elder Qu had been living with the Qu family in the Qu family's old residence.
