The word "dai" in "to wait for work with ease" in C is wrong. The correct way to write it is "to wait for work with ease".

Waiting for work is a Chinese idiom, pronounced as yǐ yì dài láo, which means to be fully prepared in war, recharge your batteries, and wait for the tired enemy to attack head-on. From "The Art of War: Military Struggle Chapter" by Sun Tzu: "Waiting near and waiting for far, waiting for fatigue and waiting for hunger, this is how to control strength."

Allusions about waiting for work in leisure:

At the end of the Western Han Dynasty, the Longgan-Gansu warlord Kui Xiao left Liu Xiu and went to seek refuge with Gongsun Shu, who proclaimed himself emperor in Sichuan. Liu Xiu was furious and sent troops to attack Wei Xiao, but was defeated by Wei Xiao.

Liu Xiu then sent Feng Yi, the general who conquered the west, to occupy Quyi. After Wei Xiao received the news, he ordered his generals to immediately go to Quanyi to seize favorable terrain. After Feng Yi's generals found out, they all advised Feng Yi not to fight with the patrolling army. Feng Yi said categorically: "We must seize the city and wait for work." Feng Yi ordered his troops to march quickly and occupied the city before the patrol.

Feng Yi strictly blocked the news, closed the city gate tightly, stopped all activities and drums, and allowed the soldiers to rest. Just as the patrolling troops hurriedly arrived at the city, drums suddenly sounded loudly on the city tower, and Feng Yi's flag was displayed. The patrolling troops were defenseless and fled in all directions. Feng Yi opened the city gate, led his troops and rushed out of the city, defeating the enemy.
