lay exposed/open to attacks on all sides
Xiang Yu and Liu Bang originally agreed to take the east and west of the gorge (in present-day Rongxian County, Jia Luhe) as the boundary, and they did not invade each other. Later, Liu Bang followed the advice of Sean and Chen Ping, and thought that Xiang Yu should be destroyed when he was weak. Then he chased Xiang Yu's army with Han Xin, Peng Yue and Liu Jia, and chased Pengcheng (now Xuzhou, Jiangsu) eastward. Finally, several layers of troops were arranged to tightly surround Xiang Yu (in the southeast of Lingbi County, Anhui Province). At this time, Xiang Yu's soldiers were few and there was no food. In the evening, when I heard the troops around him singing the folk songs of Chu, I couldn't help but be very surprised and say, "Did Liu Bang get Chu?" Why are there so many Chu people in his army? "Say, the in the mind has lost the morale, then get out of bed and drink in the camp; Sing with his favorite concubine Yu Ji. After singing, I cried, and everyone around me was very sad, and they all felt that they could not lift their heads. After a while, Xiang Yu got on his horse and escaped from the south with only 800 cavalry. Run away and fight, commit suicide by Wujiang River. Because there is a story in this story that Xiang Yu was surprised to hear the songs of Chu songs around him, and then failed to commit suicide, people later used "besieged on all sides" to describe the personnel environment where people were attacked or persecuted from all directions, resulting in an embarrassing situation of isolation and helplessness. Anyone caught in this situation often has a tragic fate. For example, some people are idle because they often associate with bad people. But later, he was forced to make a living by those bad guys. When he asks for help from others, others will never sympathize with him or ignore him because of his bad behavior on weekdays. This man's situation is "besieged on all sides". Another example is that when the school discusses academic issues, students are ignorant (idioms, meaning no academics), irresponsible and confuse right and wrong. When students rise up and attack, students are completely isolated. This can also be called "besieged on all sides". In our life, in our daily life, we should be a good person and do things in a down-to-earth manner. If you make a mistake, you will be "besieged on all sides."
The siege of Deng Bai
The siege of Deng Bai was an event in 200 BC (the seventh year of Emperor Gaozu) when Emperor Gaozu Liu Bang was besieged by Xiongnu in Deng Bai (now Mapu Mountain in the northeast of Datong City, Shanxi Province).
In 20 1 year BC (the sixth year of Emperor Gaozu), Han Wangxin rebelled in Datong, colluded with Xiongnu and attempted to attack Taiyuan. Emperor gaozu Liu Bang personally led 320,000 troops to meet the Xiongnu, first winning in Tonggong (now Qin County, Shanxi Province) and then pursuing Loufan (now Ningwu, Shanxi Province). It was a cold winter and it snowed heavily. Liu Bang ignored Liu Jing's advice and stopped him. He rushed forward and chased Datong Pingcheng. The result was lured by the Huns. Liu bang and his vanguard troops were besieged in Dengbaishan, Pingcheng for 7 days and 7 nights, and completely cut off contact with the main force. Later, Liu Bang used Chen Ping's stratagem to bribe his wife, E Shi, to escape.
After the siege of Deng Bai, Liu Bang realized that it was not advisable to solve the dispute with Xiongnu only by military means. Therefore, for a considerable period of time, adopting the policy of "pro-marriage" has become the main means to win over the Huns and maintain border peace.
