In the first year of Tang Jianzhong (780), after Emperor Shi Li of Dezong ascended the throne, the buffer region rebelled. Wu Xianxiu, the minister of the Ministry of Housing, wrote a letter requesting a decree, willing to lead the troops against the chaos in the four towns. Dezong knew that Wu Xianxiu's nephew Wu Shaocheng had rebelled, so he was not allowed to take orders. Dezong returned to Beijing after pacifying the rebellion in the buffer region, and reused Pei Yanling in the court. Pei Yanling used the rebellion in the buffer region to implicate Wu Xianxiu, attacked Xianxiu with ulterior motives, and planned a fierce struggle to usurp the throne and seize power. Emperor Dezong was afraid that virtuous performances would be tiring. Yao Nan sent a secret imperial edict to Xianxiu to avoid Joan, but Xianxiu refused to accept it, saying, "Our ancestors were all guardians of the Tang Dynasty. Is it because I have served Su Zong, Dai Zong and De Zong for more than 40 years that I will not protect the Tang Dynasty now? " To this end, he persisted in the struggle against adultery until the spring of the twenty-first year of Tang Zhenyuan (805) and the eve of the collapse of Emperor Li Shidi. Pei Yanling, the prime minister at that time, monopolized the power in the DPRK and demoted Xian Xiugong to a family in Leizhou, Guangdong Province, which dampened the righteousness in the DPRK and made Xian Xiugong in a difficult situation. Emperor Dezong was afraid that publicity (Xianxiu) would be harmful, and once again secretly ordered Xianxiu to avoid Joan of Arc. Xian Xiugong thought that sticking to good deeds could not bear to leave the DPRK. While hesitating, he went to Yangshan with a letter to discuss with his best friend Han Yu. Legend has it that he suddenly heard the cry of "grass grows in the air and jade grows in the air" in the middle of the night. Han Yu knew that Cao Su was Xiao, Tusi was the wall, Zou Bi was evasive, and Yu Jing was Joan. Today's disaster started with a small wall, just to avoid disaster arrival to Joan. Allah Tantou
In the first month of the first year of Tang Yongzhen (805), Dezong died, and Emperor Li Yong of Shunzong acceded to the throne. He learned about the merits of virtue and showed off the public, and gave special favor to Wu Xianxiu, a senior minister of the household department, that is, "Deze was born in China, named in China, and honored in the whole country." He cast bronze seals on all sides, carried them with him, showed off to the public, and had a clear order to protect the commons. Therefore, Xian Xiugong decided that in the autumn of that year, together with Mrs. Wang Yipin, his third son and his eldest son-in-law Taichang Zhengqing Wang Zhen, his family left Chang 'an, entered Qiongshan via Fujian, and settled in Duhua Village, Zhangwu Town, Qiongshan, which is now Dalin Ancient Town, Lingshan Town, Meilan District, Haikou City (Zhu Ya County, Guangdong Province in the Tang Dynasty). Tuduhua Village in Zhangwu is a good place with flat terrain, fertile land and beautiful mountains and rivers. They were warmly welcomed by local officials and ordinary people. The public built a courtyard with three pavilions and two pavilions here, and placed two bronze medals, imperial edicts and classic calligraphy and painting, which spread the culture of the Central Plains and constantly changed the face here. Duhua Village in Zhangwu has become a very famous place, and people from far away live here constantly, which makes Duhua Village a densely populated village. Under the influence of Xian Xiugong, agricultural production developed rapidly, economy prospered and culture developed, and the Dalin market gradually formed. The temples and ancestral halls of luxury houses have been built, and running schools has become a common practice. The Central Plains culture spread by Xianxiu Palace in Qiongzhou has spread all over Qiongzhou. In the thirty-fifth year of Jiajing (1556), Zhao Wenhua, the minister of the Ministry of Industry, sent a letter to inspect the south of the Yangtze River to learn about the development of Dalin in Qiongzhou, and told Emperor Jiajing that he had given a stone tablet of "Dalin, Guancheng" to praise Xian Xiugong's pioneering achievements in developing Qiongzhou's economy and culture, which hung on the streets of Dalin market and shone brightly. ? Although Xian Xiugong had only been in Qiong for three years, he died in the second year of Tang Yuanhe (807). The imperial court sent Gao Chongwen to choose a place and a date, and in the fourth year of Tang and Yuan Dynasties (809), he buried the postgraduate entrance examination in Qiongshan to play the role of a phoenix dragon lying on a slope and sitting in the land of Kunxianggen Feng Shui. During the Jiajing period of the Ming Dynasty, a stone grave was built in the tomb with the inscription "Tomb of Mrs. Wu, a senior minister in the Tang Dynasty", and the inscription on the right side was "To the descendants of Dr. Scholar, to be rebuilt". In front of the tomb stood a stone man. It was later destroyed. It was rebuilt in the 12th year of Jiaqing (1807) and completed in the 14th year of Jiaqing (1809). The tomb is surrounded by stone, with two stone lions on the left and right, a stone railing on the front and a pair of stone flagpoles outside, which is quite large. Since the reform and opening up, a group of well-known entrepreneurs, overseas Chinese leaders, overseas Chinese and their hometown folks on the island have donated more than 300,000 yuan, which was rebuilt twice 1989 and 1996. The tombstone is engraved with the words "Tomb of Mrs. Wu Xianxiu's Wang Gong", and the words "Dade, Renhe and Imperial Capital" are written on the left and right sides of the tombstone. "After death, heroic spirit protects children and grandchildren and benefits the people." In front of the tomb, there is a high-sacrificial pot pavilion with double eaves and a quadrangular pyramid-shaped roof pavilion on each side. 1September 1986 17, Qiongshan County (now Haikou City) People's Government designated the tomb as a county-level key cultural relics protection unit. Every year in Tomb-Sweeping Day, tens of thousands of clansmen and overseas Chinese come to worship their ancestors, respect clansmen and gather clansmen to unite and promote the development of Hainan's economic and cultural undertakings.
