Tan Daoji, a famous soldier in the Northern and Southern Dynasties, died on the battlefield in Ma Rong.

Tan Daoji (? -April 9, 436), famous in the Southern Dynasties. Han nationality, ancestral home of Gaoping Jinxiang (now Tanzhuang, Buji Township, Jinxiang County, Shandong Province), Jingkou (now Zhenjiang, Jiangsu Province). Out of poverty, he joined the army for more than 20 years and rose from a soldier to a general. At the end of the Eastern Jin Dynasty, Emperor Wu of Song attacked the later Qin Dynasty, and repeatedly made meritorious military service. The late Emperor Wen and his former imperial ministers were good at fighting and killed them. Tan Daoji, despite my hectic behavior, has an excellent record. Based on years of war experience, he summed up 36 plans, leaving a valuable legacy of military works for future generations and being recorded in history.

During the Northern and Southern Dynasties, wars often occurred between the southern imperial court and the countries established by the northern minorities, especially during the Liu and Song Dynasties. In AD 43 1 year and AD 1 year, Wendi failed in his northern expedition to Wei in the Southern Song Dynasty, and the advanced general retreated to Yan Zhi and settled in the Huatai area of Henan.

A generation of famous Tan Daoji led the troops to rescue, defeated Wei Jun and went to Jinan, Shandong Province. While singing vigorously, Wei made Shu light ride to burn the grain and grass. "The three armies don't move, and the food and grass go first." In the battle of Guandu, Yuan Shao was burned because of Wu Chao's grain and grass, which triggered a chain reaction and was finally defeated by Cao Cao. Tan Daoji is worried. Besides, he has just reported that several soldiers on his own side have defected to the enemy. Jiang Wei got the news and led an army to follow him. He was secretly worried. After careful consideration, he had an idea.

That night, the Song Jun military camp was brightly lit, and Tan Daoji led a group of soldiers in charge of food to check some food in a camp. Some soldiers sang and counted with bamboo pieces in their hands (an ancient counting tool, which began in the Spring and Autumn Period and was replaced by abacus in the Ming Dynasty), while others measured rice with buckets. In fact, what Tan Daoji measured in the camp was not white rice, but a bucket of sand covered with only a small amount of white rice. Someone sneaked into the camp and saw that the bag was full of snow-white rice. When spies in Wei Bing saw it, they flew back to report it. When Kang An got this information, his first reaction was that he was cheated by Song Bing who surrendered in front of him. In a rage, he killed the surrendered soldier.

Early the next morning, Tan Daoji, dressed in casual clothes, rode a carriage and led the team south along the highway. An Jie thought that Tan Daoji used the tactics of luring the enemy in depth, did not dare to catch up, and watched the Confederate army leave calmly. This is the origin of "singing for sand" and the first idiom Tan Daoji left for later generations.

Tan Daoji, who had ups and downs all his life, left other idioms for later generations besides "singing and preparing sand".

Tan Daoji's ancestral home is Gaoping, Shandong and Zhenjiang, Jiangsu. His parents died when he was a child, and he wandered with his brothers and sisters. Born in troubled times, Tan Daoji in his twenties joined the famous Emperor Wu of Song with his brothers Tan Shao and Tan Zuo. Since then, an invincible war career has begun. During the period of suppressing the rebellion in Sun En and Huan Xuan, Tan Daoji became famous and was awarded the fifth class merit in Xing Wu County.

In 4 16, emperor Wu of song led the Jin army to attack the late Qin dynasty. Tan Daoji, then a general, went red all the way, crossed the elevation (now Xingyang, Henan Province) and attacked Luoyang. After August of the following year, Qin died.

After Emperor Wu of Song usurped Jin Jiansong, Tan Daoji, as a pillar of the country, made great achievements in both east and west. After the death of Emperor Wu of Song Wudi, the throne passed to his third son, Liu Yilong Song Wendi, after his sons Liu Yifu and Liu Yizhen. Because of his high reputation, his sons are also in charge of military power, and all ministries will be brave and good at fighting. Song Wendi, who has always been "smart and patient", is very uneasy about this. Coupled with the provocation of the DPRK minister, Song Wendi began to have the mind to get rid of Tan Daoji, but because of his hard work and efforts, there was nothing he could do. Liu's cronies also believe that Tan Daoji can control the situation with Wendi. Unfortunately, Song Wendi was ill, and Doctor Tai sent several critical notices. After consulting with Emperor Wendi's four brothers, Liu Zhan, Stuart Liu Yikang and the leader, he pretended to be an imperial edict and called Tan Dao Ji into the court. He first removed his office, and then sent someone to arrest him and put him in jail. To Tan Daoji's surprise, the court actually declared him guilty of "treason".

Tan Daoji has always simply hoped that he could play for the battlefield of Yuan, the general of the Eastern Han Dynasty. But as long as the crime of rebellion is established, not only can you not go into battle to kill the enemy, but even your family will be killed. So, at that time, he was angry and hated. He took a sip of welcome wine (a welcome can hold five buckets of rice), then took off his hat and threw it on the ground, his eyes burning. It turns out that the history book is "burning with anger", which is the second idiom about Tan Daoji.

On April 9, 436, Tan Daoji was killed. Before his execution, he growled, "This is the Great Wall of Wan Li." According to legend, after Tandaoji's head fell to the ground, a lot of white hair grew after the Beijing earthquake, which just answered the nursery rhyme "Poor white floating pigeon, killing Tanjiangzhou in vain". Since then, people often compare themselves to weakening their own strength or destroying their own career, which is called "self-destruction of the Great Wall", which is the third idiom Tan Daoji left to future generations.
