In the spring of the second year of Guangde (764), Yan Wu re-suppressed Shu, and Du Fu returned to the cottage, after being adrift for nearly two years. Yan Wu recommended Du Fu as a member of the inspection department, and became Yan Wu's staff officer, and later generations called Du Fu Du Gong. Soon Du Fu resigned again.

In the past five or six years, Du Fu sent people under the fence, and life was still very hard, he said: "The book of the old man of Houlu is cut off, and the hungry and childish child is desolate" ("Crazy Husband") "The idiot does not know the father-son etiquette, and he cries angrily at the east gate." He used some details of life to show the hardships of his life, he said that his children who are not sensible do not know how to respect their father, do not know the etiquette of the master, when they are hungry, whether they are fathers or not, whether they want to follow the etiquette of father and son, when they are hungry, they are clamoring for food, crying outside the east gate, and in the autumn storm, Du Fu's thatched hut is dilapidated, hungry old wife, sleepless all night, he wrote "Song of the thatched hut broken by the autumn wind".

In April of the third year of Guangde (765), Yan Wu died, and Du Fu left the CD. After passing through Jiazhou, Rongzhou, Yuzhou, Zhongzhou, and Yun'an, it arrived at Kuizhou (Fengjie) in the first year of the Tang Dynasty's Great Calendar (766). Due to the care of Bai Maolin, the governor of Kuizhou, Du Fu was able to live here temporarily, managed 100 hectares of Dongtun public land for the government, rented some public land, bought 40 acres of orchards, hired a few hired workers, and participated in some labor with his family.

During this period, Du Fu's creation reached a climax, and in less than two years, he composed more than 430 poems. During this period, his works include "Happy Rain on a Spring Night", "Song of the Thatched House Broken by the Autumn Wind", "Shu Xiang", "Wen Guanjun Collects Henan and Hebei", "Ascending", "Ascending Yueyang Tower" and a large number of famous works. One of the most famous poems is: "There are thousands of mansions in Ande, and the poor people in the world are happy." And in "Ascending": "Boundless falling trees and Xiao Xiao, endless Yangtze River rolling" is a swan song for the ages.

In the third year of the Great Calendar (768), Du Fu was homesick, took a boat out of the gorge, first to Jiangling, then to the public security, and at the end of the year drifted to Yueyang, Hunan, during this period of time Du Fu has been living on the boat. Due to the difficulties of life, not only could they not return to the north, but they were forced to travel further south. In the first month of the fourth year of the calendar, from Yueyang to Tanzhou (Changsha), and from Tanzhou to Hengzhou (Hengyang), it turned back to Tanzhou......

Recalling the untimely and upheaval life of a generation of great writers Du Fu, Zhang Cambodia couldn't help but feel nostalgic for his life experience, sadness came from it, and he couldn't help but look up to the sky and sigh: "Everything in the world can be good, only articles are not valuable!" ”

"Ah, Lotus, out of the mud without staining ......!" Zhang Cambodia looked at the lotus flower in the pond blankly, his mind was long, he couldn't help himself, and fell into the lingering memories of the past......

Zhang Cambodia has loved lotus flowers since he was a child. When he was a little sensible, he dug up some lotus roots in the pond in the back garden of his house and planted them in the pond, and soon the pond was full of lotus flowers.

As early as when he was in private school, he knew that the lotus flower was not stained by mud and was a spiritual symbol of being a human being. Since then, Zhang Cambodia has the opportunity to go to the pond to see the different beauty of the lotus flower "out of the mud without staining".

When he was a teenager, he often read books alone in the shade of the lotus pond, and when he was tired, he looked at the lotus pond, thinking about the lotus flower in a daze, thinking about Sui? The scene of Du Gongzhan's "Song of Concentric Hibiscus Poems":

Scorching lotus flowers, pavilions out of the water.

One stem is lonely and green, and the two shadows share dividends.

The color grabs the face of the song, and the fragrance dances in the style of clothes.

The name lotus can be read by itself, and the situation is the same as the two hearts.

When the shadow of the years gradually lengthened, he had a very small chance to read a book by the lotus pond in the courtyard of his home.

Because Zhang Cambodia was involved in scriptures and historical books, at the age of 16, he filled the vacancy as a student. The sacrificial wine made Hu Deqi think that he was a genius, so he expected him as an auxiliary minister of the emperor. Due to the tight homework, he never returned home to read by the lotus pond, and never had the opportunity to look at the lotus pond and think about the lotus flower.

After being a sergeant, Zhang Cambodia was initially transferred to Qingyuan County. In the first year of Yongchang (689), the imperial court called for the examination with virtuous subjects, and Zhang Cambodia ranked first. Awarded the official to supervise the imperial history, and later moved to the Fengge house.

At this time, the Turkic leader silently asked for his daughter to marry, and Wu Zetian wanted Wu Yanxiu to marry her. Zhang Cambodia said: "Since ancient times, there has never been a matter of a son of heaven marrying a woman of a different race. "Violated Wu Zetian's will and was transferred out of the imperial court Renhe and Shu Erzhou Assassin History. In the old case, 500 soldiers were sent to garrison Yaozhou every year, and there was a miasma here, and he would die here.

Zhang Cambodia's strength Chen Chen his shortcomings said——

The minister researched Yaozhou, which is an ancient mourning country, located outside the Eight Wilderness Territory, with dangerous mountains and dangerous waters. During the Western Han Dynasty, there was no communication with China, and during the time of Emperor Wu of the Han Dynasty, Tang and Meng opened up the road to Yelang, Yunnan and Zhen, but they did not belong to the prison. At the end of Guangwu in the Eastern Han Dynasty, it asked to be accepted as a subject country and set up Yongchang County to govern it. Its salt, cloth, felt carpets, and woollen fabrics were levied in favor of China. It is adjacent to Daqin in the west and Jiaozhi in the south, and there are plenty of rare tributes. Liu Bei occupied Shu and was short of armaments, so Zhuge Liang crossed Lushui in May, expropriated its property to replenish armaments, and sent Zhang Boqi to select strong soldiers to strengthen his troops. Therefore, "Shu Zhi" said that after Zhuge Liang's southern expedition, Shu was rich. The previous dynasty set up a county here because it was advantageous. At present, its salt, cloth and other taxes are not provided, rare tributes are not entered into the court, weapons such as halberds do not enrich the army of our dynasty, and local assets are not dedicated to the great powers of the Celestial Empire. However, the imperial court exhausted the official property, drove and led the people to be subjected to barbarian servitude, and died miserably. The ministers feel sorry for His Majesty.

In that year, the envoys of the Eastern Han Dynasty crossed the Bonan Mountain, crossed the Lancang River, and reestablished the two counties of Bonan and Ailao. The people of Shu were sad about this, and the envoy sang: 'Yue Bonan, pass through Lanjin, cross Lancang, for others. It is a satire of being enslaved by barbarians for the sake of greedy for the benefit of rare goods. The Han Dynasty gained its benefits, and the people still sang grievances. Now it is the depletion of the national reserves, and the expenditure and household taxes are shrinking day by day, so that His Majesty's people can fatten the weeds with their bodies, and the bones cannot be returned, so that the old mother and the young son can only wail and sacrifice thousands of miles away. The court has no interests, but the people have suffered for life, and the ministers are selfish and sad for the country.

In the past, Zhuge Liang captured Nanzhong and appointed its leader to govern on the spot, without Han officials and no garrison soldiers. He thought that there were three difficulties in setting up officials and retaining soldiers: the establishment of officials would inevitably cause Han Chinese and indigenous people to live together, which would cause suspicion and resentment; Leaving troops to transport grain and grass will make the disaster worse day by day; In the future, a sudden rebellion will inevitably cost the people and money. Therefore, the rough enactment of laws and regulations is regular, and it is natural to be stable for a long time. The minister thought that Zhuge Liang's strategy had indeed exhausted the outline of the barbarians. Today's officials in Yaozhou have neither the consciousness of strengthening the border defense to suppress foreign invaders, nor the ability of Zhuge Liang to capture and indulge, but only extort and extort, plunder and mutilate at will; incitement their leaders into sectarian formations; or groveling, flattering the barbarians, bowing and bowing respectfully, and no longer ashamed; or lead their disciples and protégés, gather fierce and ignorant people, gather people to gamble, and spend thousands of dollars. In total, there were more than 2,000 criminals who fled to Yaozhou, specializing in robbery. At the same time, Yaozhou was originally set up by Shi Ziren, the main book of King Wuling during the Longshuo period, and then Li Xiaorang and Xin Wenxie died in the hands of the aborigines; Zhao Linglang sent Zhao Wugui to the crusade, and the soldiers did not survive; He also sent the general Li Yiwei to continue to go to the campaign, and Lang killed Liu Huiji in battle, and the state was abolished. The minister privately thought that Zhuge Liang's 'three difficulties' had all come true.

During the vertical arch year, the local ethnic Lang general Wang Shanbao and Queensland Thorn Shi Qianfu once again asked to set up a state here, claiming that the taxes were self-sufficient and not taken from Shu County. After the state was established, Li Xuan, the state peng, was killed by the barbarians. In the middle of the extended year, Sima Chengchen set up seven towns in Lunan and sent Shu soldiers to garrison them, and Shu County was in chaos.

At the same time, the fifty-seven prefectures under the jurisdiction of the Yaozhou Governor's Office were all extremely cunning exiles. The state appoints officials to correct the people's morals and prevent rebellion, but the shameless officials are so corrupt and absurd. So far, the calamities have not stopped, and I am afraid that the calamities that will shock the country and disturb the people will grow day by day. Yaozhou should be abolished, and Ailao should be subordinated to the Governor's Mansion of Shanzhou, and its leaders and envoys should meet the Son of Heaven on time every year, and they should be regarded as foreigners; Abolish the towns of Lunan, and set up a garrison in Lubei, who is not an envoy of the imperial court, and is not allowed to associate with them; Increase the garrison of Shanzhou, and select honest and virtuous officials to govern it. His subordinates thought it would be beneficial.

Zhang Cambodia's recital was not accepted. Soon he was transferred to serve as the governor of Jingzhou.
