Cui Shi's book provides descriptions of rituals for ancestor worship, festival and religious holiday celebrations, conduct for family and kinship relations, farmwork, and the schooling season for boys. Cui Shi's book also provides detailed instructions on which months were the most profitable times to buy and sell certain types of farm-produced goods. The following table is modelled on Ebrey's "Estate and Family Management in the Later Han as Seen in the Monthly Instructions for the Four Classes of People" (1974). Ebrey writes: "... the same item was often bought and sold at different times of the year. The rationale for this is very clearly financial: items were bought when the price was low and sold when it was high." The specific amounts for each commodity traded are not listed, yet the timing of sale and purchase during the year is the most valuable information for historians.
