Whipping horses to transport food means.

"The whip urges the horse, but he is busy transporting grain" is an idiom, which means to speed up and complete the task as soon as possible in an emergency. The origin of this idiom can be traced back to the ancient agricultural society in China. At that time, farmers needed to harvest crops as soon as possible during the harvest season, and then transport them home for storage for future needs. In order to complete this task as soon as possible, farmers will ride horses and whips to speed up transportation, so as to complete the transportation task as soon as possible. Later, this idiom was extended to speed up and complete the task as soon as possible in any emergency.
