Su Yunjin's family kitchen had everything, flour, pork, condiments, you name it, and perhaps even more complete than what the Chu family had.
Since she had all the ingredients at hand in her room, when teaching Mrs. Chu how to make buns, Su Yunjin didn't plan on going back to the old Gu residence to teach. Going there would likely mean encountering Mrs. Zhang and those other irritants. Having finally moved out of the old Gu house, Su Yunjin certainly had no intention of going back without good reason.
She would teach Mrs. Chu how to make buns right at her home, which was convenient and saved the hassle of running back and forth with Mrs. Chu.
As Su Yunjin taught Mrs. Chu to make buns in the kitchen, Gu Yan did not linger to watch. After having breakfast, he left the house. As for what exactly Gu Yan went out to do,
Su Yunjin didn't know.
