What are the famous' historical allusions and idiom stories' in Qi during the Warring States Period?

One day in the sun and one day in the cold-work hard for one day and do nothing for ten days.

During the Warring States period, a hundred schools of thought contended and lobbied vigorously. The average lobbyist is not only knowledgeable, but also has profound and vivid metaphors to satirize and persuade the rulers, which is the most prominent. Mencius was also a famous debater. In the first article of Mencius, Gao Zi, there is such a record:

Mencius was dissatisfied with Qi Wang's fatuity, lack of perseverance, and credulous adulterer's slanderers, so he said to him rudely, "Qi Wang is so unwise. Although there are living creatures in the world, you exposed them to the sun for a day, but frozen them in a cold place for ten days. How do they survive there? " My time with the king is very short. Even if the king has a little determination to be good, as soon as I leave you, those traitors will come to trick you and you will listen to them. What should I do? Based on this, he made a vivid analogy: "Playing chess seems trivial, but if you don't concentrate, you won't learn well and you won't win. Qiu Yi is the best chess player in the country. He taught two apprentices, one devoted himself to listening to Qiu Yi's guidance everywhere; The other is always afraid that a big swan will come and prepare to shoot the goose with an arrow. Both apprentices were taught by a master and studied together, but the latter's grades were far from each other. This is not the difference of their intelligence, but the difference of their concentration. "This is a very instructive story. If we want to learn something and do it well, we must concentrate on it and work hard. If you do something today, forget it and do it for ten days the next day, how can you do it well? Success in learning and doing things is also one of the decisive factors, so people later simplified what Mencius said as "one day's violence, ten days' cold" to the idiom "one day's violence, ten days' cold", which was used to describe the lack of perseverance in learning and doing things and giving up halfway. For example, a classmate is very casual about learning, and he spends less time studying and more time wasting.

Encircling Wei to save Zhao-Encircling Wei to save Zhao

In 354 BC, Wei's army surrounded Handan, the capital of Zhao. The two sides fought for many years, and Zhao was weak and Wei was tired. At this time, Qi responded to Zhao's call for help, and sent Tian Ji as the general and Sun Bin as the strategist, leading 80,000 troops to save Zhao. Where is the attack direction? At first, Tian Ji prepared to go straight to Handan. Sun Bin believes that to untie the tangled silk thread, you can't pull hard with your hands, and you can't directly participate in fighting with others. To send troops to clear up, we should avoid reality and get to the point. He suggested to Tian Ji that the elite troops of Wei are now concentrated in Zhao, which is empty inside. If we lead the troops into the capital girder of Wei, occupy its traffic arteries, attack its empty space, and March into the capital girder of Wei (now Kaifeng, Henan), Zhao's Li will be spared to save himself, while the Qi army will take advantage of its fatigue to meet the returning enemy in Guiling, a pre-selected combat area. Wei Jun was defeated, and Zhao Zhiwei was solved. Sun Bin's method of besieging Wei to save Zhao is a famous example in the history of China, which was listed as an important one of the 36 strategies by later military strategists. The method of encircling Wei to save Zhao, avoiding reality and avoiding emptiness, has been appreciated by military strategists in past dynasties and still has vitality today.
