The Fifth Uncle also sent a message to his family, asking Yan Lingzhou to live at his place in town for a while. He had also offered to guide Yan Lingzhou with his studies so that he wouldn't miss the Imperial Examinations in the spring.
If it wasn't for the fact that his great-grandfather was in poor health, his father not being home, and his third and fourth uncles were too busy earning money in town. He would have gone to town to live with his fifth uncle.
If Gongyu Mingxi's knowledge was really on par with Yan Yongwu's, Yan Lingzhou could stay in the village and study. He could still look after the family and urge his younger brothers to study, which was better than going into town to study with his fifth uncle.
Now that his family was making tofu, his third and fourth uncles didn't have to go into town to work part-time anymore. He was the eldest grandson of the family, so he could still help his family by staying home.
