Zhou Shuren called his two sons and Rongchuan, carefully moved the books out first and put them away, then took out the writing brush, ink, paper, and inkstone. There was only one set of valuable writing materials, which Zhou Shuren kept for the imperial examinations. There were three sets that were slightly inferior, each worth about ten taels of silver, but it would cause jealousy if he gave them to the children to use; thus, he kept them as well. What he distributed to each of the three children was bought with silver coins, a set worth one tael, but these too could only be used at home, while they would still use cheaper ones when studying outside.
