The so-called "Nan" or "Zi Nan" is "Southern Chinese Characters", which is created by imitating Chinese characters, borrowing the structure of Chinese characters, and expressing Vietnamese in the form of pictophonetic characters, knowing words and borrowing Chinese characters. For example, in Chinese, the phrase "I have three years to study" is written as a "solid reader". /kloc-in the 0/4th century, some literary works written in southern languages appeared in Vietnam. Zhu Wenzhen writes poems in Mandarin. Han Quan is good at Chinese poetry and Fu, and there are many Chinese poems in his Pipa Collection.
The popularity of Nanzi reflects the enhancement of Vietnamese national consciousness. Tr?nngh?· Tang (Chen Fang, 1370 ~ 1372) even told the soldiers and civilians of 1374 not to dress like northerners (China people) and effectively occupy (occupy) and prison (Laos) languages. This narrow feudal national consciousness has developed to the extent of rejecting foreign cultures. Backed by its relatively strong political and economic strength, Vietnam's Chen Dynasty constantly strengthened its military strength. As a result, the Chen Dynasty not only defeated the Yuan Army's three expeditions, but also launched several large-scale invasions on Zhancheng and Laos.
In A.D. 1305, the ruler of Zhancheng (Ye He Ba Maw III) attempted to ease the relationship between the two countries through "intimacy" and prevent further invasion by the Chen Dynasty. 1306, Chen Yingzong (1293 ~ 13 14) used his sister "the princess to marry the king of the city" and used the cession of Wu and Li as a "dowry". 1307, the Chen Dynasty renamed Uzbekistan and Bali as Zhou Shun and Huazhou (equivalent to Guang Zhi and Chengtian areas of Yue).
1307 After the imperial system that occupied the city perished, the Chen Dynasty used the new imperial system that occupied the city as an excuse. In 13 12, Chen Yingzong invaded the city and plundered the imperial system, "sealing his brother to make Tuo 'apo stick to Yahou town". In the autumn of 13 18, the kingdom was sent to seize the city. At first, the soldiers were defeated. Later, five old soldiers of Guantian Wu Junfan will surround them from the back road. The army was defeated and many people were captured.
1376 winter, Chen (1372 ~ 1377) rate120,000 troops occupied the city on a large scale. 1377 At the beginning of the year, in the battle against the occupied city of Wang Zhuocheng, Chen Jun was isolated, intercepted by the occupied army and defeated by zhan wang. Chen was killed, so were General and Ruanna. During the period of Chen Shunzong (1388 ~ 1398), in the winter of 1388, General Li was ordered to meet a crushing defeat. However, in a water war at the beginning of 1390, Zhan Wang Peng 'e was killed because of a traitor's informer, and the army was defeated. After that, Zhancheng (Zhanpo) declined sharply and was gradually annexed by Vietnam. In order to dominate Indo-China Peninsula, Chen Chao also invaded its western neighbor Laos (called Ailao or Niuhouman in Vietnamese history). /kloc-in the winter of 0/298, Chen Yingzong lost his life in prison and lost his soldiers.
In A.D. 1334, Chen "led the army to Qianzhou, and Lu Dazhen led the army and fled in the wind". He specially ordered the accompanying blue-and-white boat to make Ruan Zhongyan grind a cliff and erect a monument on the mountain in Shenxiang Village, Xiangyang County, Yi 'an. The inscription reads: "Calligraphy and painting are big and deep." In his words, he said, "The Emperor is the sixth emperor of the Chen Dynasty ... He was chosen in the midsummer by heaven, and he is very poor at home and abroad. He refused, he mourned, and he was still the king. 18-year-old, Yi Haiqiu, the sixth division of Emperor Qin Shuai toured Xibi, occupied the city country, the prince, the real wax country, the Siam country, the minister of Manchu Road, the sunflower birds, and the newly attached cups, pots, Manchu Road, music and cars, all of which performed their duties and rushed to meet the enemy, but they did not come to the DPRK immediately. In winter, the emperor was stationed in the original residence of Jutun in Mizhou. He ordered the generals and barbarian soldiers to enter his country and flee against the wind, so he surrendered to his troops. " The "merit" recorded in the inscription is an ironclad proof of Vietnam's feudal rulers' foreign aggression and expansion.
/kloc-in the winter of 0/329, Chen Xianzong personally levied a cow roar and mourned for the collapse. /kloc-in the autumn of 0/336, Chen Xianzong "wanted to show off Wuwei" and sent troops to mourn the army again, only to be ambushed, with more than half of the casualties and defeat.
