What do you mean, sow widely and reap sparingly, and live easily?

1. The meaning of "expanding the field and keeping enough" is: using horses to cultivate land well means overqualified and wasting talents.

2. Notes; "Expansion" means "expansion and reclamation"; "Yi Zu" refers to a fine horse-the biography of Xie Zhuang in Song Dynasty: "The sharp scenery of clouds is Yi Zu." Qi's poem "Car Passing Eight Hills" says: "Drive comfortably and fly."

3. The synonym of "wide planting and thin harvest, easy to get enough" is: "kill the chicken with an ox knife".
