It turns out that Xue Chu's home is located in the alley opposite Sheng'an Hall, and Xue Chu said that Sheng'an Hall is a hereditary pharmacy, passed down through generations, now run by a father and son.
Xue Chu knew the pharmacy's address, saving Su Yunjin the trouble of asking around in town, which relieved her greatly. Su Yunjin happily asked Xue Chu to lead the way. Feeling bored on the road, Su Yunjin casually asked about the situation at Sheng'an Hall, and Xue Chu told Su Yunjin all he knew.
Xue Chu said that the shopkeeper of Sheng'an Hall is named Liu Sheng, over forty years old, not only meticulous in business but also sells herbs at a higher price than others.
