The Hani or Ho people (Hani: Haqniq; Chinese: 哈尼族; pinyin: Hānízú; Vietnamese: Người Hà Nhì / 𠊛何贰) are a Lolo-speaking ethnic group in Southern China, Northern Laos, and Vietnam. They form one of the 56 officially recognized nationalities of the People's Republic of China and one of the 54 officially recognized ethnic groups of Vietnam. In Laos, the Hani are more commonly known as Ho.
A terrace in agriculture is a flat surface that has been cut into hills or mountains to provide areas for the cultivation for crops, as a method of more effective farming. Terrace agriculture or cultivation is when these platforms are created successively down the terrain in a pattern that resembles the steps of a staircase. As a type of landscaping, it is called terracing.
Terraced fields decrease both erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice. The Rice Terraces of the Philippine Cordilleras have been designated as a UNESCO World Heritage Site because of the significance of this technique.
The Han Chinese are the largest ethnic group in Mainland China. In 2010, 91.51% of the population were classified as Han Chinese (~1.2 billion). Besides the Han Chinese majority, 55 other ethnic (minority) groups are categorized in present-day China, numbering approximately 105 million people (8%), mostly concentrated in the bordering northwest, north, northeast, south and southwest but with some in central interior areas.
The major ethnic minorities in China are the Zhuang (19.6 million), Hui (11.4 million), Uyghurs (11 million), Miao (11 million), Manchus (10.4 million), Yi (9.8 million), Tujia (9.6 million), Tibetans (7 million), Mongols (6.3 million), Buyei (3.5 million), Dong (3.5 million), Yao (3.3 million), Bai (2 million), Koreans (1.7 million), Hani (1.7 million), Li (1.6 million), Kazakhs (1.5 million), and Dai (1.2 million). In addition, there are a number of unrecognized ethnic groups which together comprise over 730,000 people. Collectively, the ethnic groups of China are referred to as the Zhonghua minzu (Chinese: 中华民族; pinyin: Zhōnghuá mínzú; lit. 'Chinese ethnicity'). However, being part of the Zhonghua minzu (i.e. being part of one of the 56 ethnic groups) does not necessarily mean one must have Chinese nationality (Chinese: 中国国籍; pinyin: Zhōngguó guójí) or be loyal to the People's Republic of China.
The Hani language (Hani: Haqniqdoq or xa31 ɲi31; simplified Chinese: 哈尼语; traditional Chinese: 哈尼語; pinyin: Hāníyǔ; Vietnamese: Tiếng Hà Nhì) is a language of the Loloish (Yi) branch of the Tibeto-Burman linguistic group spoken in China, Laos, Myanmar, and Vietnam by the Hani people.
Agriculture has been a cornerstone of the People's Republic of China (PRC) and its predecessors' economy and culture for millennia, supporting one of the world's largest populations and driving economic development. The country produces a diverse range of crops, including rice, wheat, corn, potatoes, soybeans, tomatoes, millet, cotton, tea, fruits, vegetables, and oilseeds. Due to limited arable land—which constitutes roughly 10% of China's total land area—intensive farming practices, innovative agricultural technologies, and efficient land-use management have historically been critical in meeting domestic food demands.
China's agricultural history dates back to the Neolithic era, with archaeological evidence showing early domestication and cultivation of rice and millet. Over the centuries, the introduction of newer agricultural technologies such as the moldboard plow, advanced irrigation systems, and crop rotation shaped society, as it generated greater agricultural surpluses. In the modern era, agriculture was notably impacted by state-led policies, including land reforms in the early years of the PRC, the collectivization efforts of the Great Leap Forward, and subsequent reforms such as the Family Production Responsibility System introduced during China's economic liberalization beginning in 1978.
