Lin Ronggui is a male supporting character, a brick and tile craftsman in Xiahe Village who has been in the business for decades. He is the only one in the surrounding villages who can make bricks and tiles, making him an important figure for anyone building a house. He lives in a spacious blue brick and tile house with a bright courtyard surrounded by a brick wall about a zhang high. His courtyard contains a vegetable garden with garlic sprouts, bean seedlings, and broad bean pods, as well as a toon tree. Lin Ronggui is portrayed as a busy and somewhat impatient man who has strict standards for his apprentices. He previously took in Qi Shan as an apprentice but had to send him away after Qi Shan started drinking while the kiln was burning, which was dangerous. He is business-minded and appreciates smart people to do business with, as shown by his interaction with Liu Guyu regarding the burnt stone powder transaction.
