Where is the Liang family tree preserved? How to write the conclusion of a research report on the history and current situation of the Liang surname

The migration history of the Liang surname. Before the Jin Dynasty, the Liang surname was concentrated in various places in the north, and the northwest was the main distribution area. During the Qin and Han Dynasties, people surnamed Liang lived scattered in Hedong (now part of Shanxi). During the reign of Emperor Jing of the Han Dynasty, Liang Lin was the prefect of Taiyuan. At the end of the Western Han Dynasty, the Liang family moved from Hedong to Beidi (today's Yaoxian and Fuping areas of Shaanxi). During the reign of Emperor Ping of the Han Dynasty, the descendants of the Liang surname were divided into two groups: one lived in Anding (present-day eastern Gansu and most of Ningxia) and the other lived in Fufeng (present-day central and western Shaanxi Guanzhong). The Liang surname moved southward during the "Yongjia Rebellion" in the Western Jin Dynasty. Liang Fang's clan crossed the river with the Jin Dynasty, and they multiplied in large numbers between Qiantang (now Hangzhou, Zhejiang) and Hepu (now Hepu, Guangdong). Later, Liang Xia Kaiji Fuzhou, Fujian, is the ancestor of Fujian and Guangdong. During the Sui and Tang Dynasties, the Liang surname had new development in the south. At the end of the Song Dynasty, when the Jin soldiers entered the Central Plains, until the Mongolian army went south, the Liang surname moved south again. By the Yuan and Ming dynasties, the Liang surname had developed into a large family in Guangdong, Fujian, and Zhejiang, and spread throughout the country. The surname Liang in Hong Kong generally comes from Panyu, Xinhui, Shunde, Nanhai and other places in Guangdong; the surname Liang in Taiwan generally comes from Jiangsu, Zhejiang and Fujian. According to statistics, before 1946, 80% of Taiwanese people came from Fujian, with the largest number of people from Zhangzhou and Quanzhou. After the Kuomintang's defeat in Taiwan, Taiwan's Han population increased sharply, accounting for approximately 89% of the island's population. Migrating overseas As far back as the Western Han Dynasty, there were Han people and Han surnames in North Korea, known as "Lelang County". During the Sui and Tang Dynasties, due to the failure of Emperor Sui Yang's three expeditions to Goryeo, a large number of Han people stayed in Goryeo as prisoners, including of course a part of the population surnamed Liang. In 892 AD, a peasant uprising broke out in Silla, and the leader of the uprising was a Silla man named "Liang Ji". Yang Ji was a local wealthy person from Xiaojing, Bukwon (now Wonju, Gangwon Province). He was dissatisfied with the social reality and took the opportunity to launch a peasant uprising. He trusted Gong Yi, a monk with a noble background, and asked him to lead troops to attack Jiuquan County in Mingzhou. Gong Yi used the power in his hands to recruit troops and expand his power, and declared his independence in 897. Liang Ji led his troops to attack Gongyi, and the two sides fought a decisive battle in Feinu City. Liang Ji was defeated and died. To this day, there are still many people with the surname Liang living in North Korea and South Korea. Table tennis player Liang Yingzi and industrialist Liang Yujing are all world-famous people with the surname Liang. Vietnam, known as Annam and Jiaozhi in ancient times, has had many exchanges with China in history and has very close ties. There are also many people surnamed Liang living here. For example, in the anti-French armed uprising of soldiers in Taiyuan, Vietnam in 1917, one of its leaders was Liang Ngoc. Liang Ngoc Kuan was originally a Vietnamese student studying in Japan. She graduated from Zhenwu School in Japan and later joined the Liberation Society of Vietnam. She was arrested by the British authorities in Hong Kong in 1915 for engaging in revolutionary activities. After being released from prison, Liang Yujuan launched a soldier uprising together with Zheng Wengen in 1917 and occupied Taiyuan City. Due to the disparity in strength between the two sides, the uprising failed and Liang Yujuan died gloriously. In the United States, from 1943 to 1965, Japan admitted 66,145 Chinese people, of which only 137 were people with the surname Liang. In 1965, the United States supplemented and revised its immigration laws, and the number of Chinese Americans increased significantly. By 1980, the number of Chinese Americans in the United States had reached 806,040. From 1981 to 1990, the number of Chinese soared from 800,000 to 1.645 million, accounting for approximately 6% of the US population. The number of Chinese surnamed Liang has not been recorded. Since Canada implemented new immigration regulations in 1967, the number of Chinese has grown rapidly. In 1967, there were 79,000 Chinese nationals in Canada, which increased to 586,000 in 1991, including 250,000 in Toronto and 150,000 in Vancouver. Since the first batch of Chinese workers from Guangdong arrived in Canada in 1858, a large number of Cantonese have begun their journey to the Americas. In particular, the "Siyi people" from Taishan, Kaiping, Xinhui and Enping in Guangdong are the largest, accounting for about the total number of overseas Chinese. 78.5% of the total volume, mainly engaged in catering, groceries, real estate, and service industries.
