Liu Sanqiang is the father of Fat Dun and a neighbor with a long-standing grudge against Lin Qinglan's family. He and Lin Qinglan's father were in the same regiment and competed for the regiment commander position years ago, which Lin Qinglan's father won due to greater military merit. Liu Sanqiang never forgave this and made sarcastic remarks behind his back after Lin Qinglan's father died. He is described as petty, spiteful, two-faced, and a schemer. His wife is described as even worse—a complete shrew. He came to Auntie Peng's house with a fake smile and a bag of sweet potatoes under the pretense of apologizing for his son's behavior, but Lin Qinglan sensed his true malicious intentions.
