Idiom story

During the Western Zhou Dynasty, after the death of Zhou Yiwang, his son Zhou Liwang ascended the throne. At that time, there was a vassal state called Rongguo in the Zhou Dynasty. Rong Yigong, the monarch of Rongguo, plundered the people's wealth and oppressed the people. This kind of bad king, who took advantage of the people, should have been spurned by the Zhou Dynasty. But Zhou Liwang appreciated Rong Yigong and thought that he was very interested in himself, so he planned to reuse Rong Yigong.

The ministers of the Zhou Dynasty knew that Rong Yigong was a greedy and mercenary man, so they advised Zhou Liwang that the appointment of such a person would lead to the collapse of the Zhou Dynasty. But Zhou Liwang didn't listen to the admonition of his ministers. Not only did Ren Rong turn Yi Gong into an official, but he also made Rong Yi Gong take charge of state affairs.

After Rong Yigong took office, he slandered Zhou Liwang and asked Zhou Liwang to implement "patent" control on all the mountains and rivers in the Zhou Dynasty, and issued a decree saying that all the trees in the mountains and rivers and all the benefits produced in the mountains and rivers in the Zhou Dynasty belonged to Zhou Liwang, and no one was allowed to make a living in the mountains and rivers in Zhou Liwang.

After the promulgation of this law, woodcutters can't go up the mountain to cut wood, hunters can't go up the mountain to hunt, fishermen can't go down the river to fish, practitioners can't go up the mountain to collect herbs, and farmers can't go up the mountain to reclaim land. Countless people have been cut off by this outrageous "patent" system. At that time, people's resentment boiled, and the "patent" aroused people's anger, and the people cursed one after another.

King Zhou Li also sent many guards to watch the people, and arrested and executed anyone who was dissatisfied with, criticized or cursed the patent. Under this kind of tyranny, everyone is in danger, and the sages are in constant fear and dare to speak out. The people were too scared to speak when they saw countless people complaining about patents killed.

After Rong Yigong and Zhou Liwang carried out the "patent", in a few years, Zhou Liwang's wealth piled up like a mountain. However, the people were in hunger and poverty, and there were starving people in rags everywhere from the capital to the countryside. The displaced hungry people are all over the countryside, just like those wild geese who are homeless in winter and can only gather in swamps and wilderness to starve and freeze, giving out bursts of wailing.
