One Set per Person

In the car, Lu Chen said: "I'm going to buy a house for each of you today. Putting aside our family, the elders will buy one. Then, each family will have one for each child. For example, your family has one set of parents, one set for you, and one for your brother and sister. "Then it will be the same for uncle's family, his son's family, fourth cousin's family, and fifth cousin's family. Sixth Uncle's seventh cousin's family will also be the same —" Lu Chen explained to Lee Tine.

He bought a total of twenty-one sets, and his relatives divided them into eighteen sets. Grandfather, Grandmother, Mrs. Lu, and one more.

"That's not good, right?" Lee Tine hesitated for a moment before she finally opened her mouth to speak.

"Why not?" Lu Chen raised his eyebrows.
