Antireligious campaigns in China refer to the Chinese Communist Party's official promotion of state atheism, coupled with its persecution of people with spiritual or religious beliefs, in the People's Republic of China. Antireligious campaigns began in 1949, after the Chinese Communist Revolution, and continue in Buddhist, Christian, Muslim, and other religious communities in the 21st century. State campaigns against religion have escalated since Xi Jinping became General Secretary of the Chinese Communist Party. For Christians, government decrees have mandated the destruction of houses of worship, such as Christian churches. In Tibet, similar decrees have mandated the destruction of Tibetan Buddhist monastic centers, of sacred Buddhist sites, of monastic residences, the denial of the Tibetan people's right to freely access their cultural heritage, and resulted in the ongoing persecution of high Buddhist lamas and of Buddhist nuns and monks. Reports of forced reeducation camps, arrests, beatings, rape, and destruction of religious sites in Tibet are likewise being made with regard to the Uyghur people, who are also allegedly being subjected to an ongoing cultural genocide.

On 14 December 2012 between 7 and 8 a.m. local time, a 36-year-old villager identified as Min Yongjun stabbed 24 people, including 23 children and an elderly woman, in a knife attack at Chenpeng Village Primary School, Wenshu Township, Guangshan County, Henan province, China.

Kidnapping in China has its history since the ancient times. Such issues have been heavily studied and discussed by investigators and researchers.

The 2008 Kunming bus bombings occurred on 21 July 2008 when explosions aboard two public buses in downtown Kunming, the capital of southwest China's Yunnan province, killed two people. The explosions were deliberate, according to police. The attacks occurred amid heightened tensions due to the Beijing Olympics. China later said the explosions were "not an act of terrorism".

After taking power in 1949, the Communist Party of China embarked upon a series of campaigns with the aim of eradicating prostitution from mainland China by the early 1960s. Since the loosening of government controls over society in the early 1980s, prostitution in mainland China not only has become more visible, but can now be found throughout both urban and rural areas. In spite of government efforts, prostitution has now developed to the extent that it comprises an industry, one that involves a great number of people and produces a considerable economic output. Prostitution has also become associated with a number of problems, including organized crime, government corruption, hypocrisy, and sexually transmitted diseases. For example, a Communist Party official who was a major provincial campaigner against corruption was removed from his post and expelled from the party after he was caught in a hotel room with a prostitute.

Shanzhai is a Chinese term literally meaning "mountain fortress" or "mountain village" whose contemporary use usually encompasses counterfeit, imitation, or parody products and events and the subculture surrounding them. Shanzhai products can include counterfeit consumer and electronic goods, which can involve the imitation and trademark infringement of brands and companies. The term's modern usage grew around 2008 when counterfeit smartphones reached their greatest domestic use. Today, some relate the term with grassroots innovation and creativity rather than with falsehood or imitation.

The 2008 Tibetan unrest was a series of protests and demonstrations over the Chinese government's treatment and persecution of Tibetans. Protests in Lhasa by monks and nuns on 10 March have been viewed as the start of the demonstrations. Numerous peaceful protests and demonstrations were held to commemorate the 49th anniversary of the 1959 Tibetan Uprising Day, when the 14th Dalai Lama escaped from Tibet. The protests and demonstrations spread spontaneously to a number of monasteries and throughout the Tibetan plateau, including into counties located outside the designated Tibet Autonomous Region. The arrest of monks at Labrang Monastery increased the tension of the situation. Violence began when Chinese police and People's Liberation Army units used force on non-violent protests by monks and nuns, and spread when protesting Tibetans later clashed with security forces. Clashes also occurred between Tibetans and Chinese Han and Hui residents, resulting in Han and Hui stores and buildings being destroyed and numerous Chinese civilians being injured or killed.

The Yilishen Tianxi Group was a Chinese company established in 1999 which sold traditional Chinese medicine products made from ants. More than one million people invested money in the company, purchasing and raising boxes of ants with the promise that they could sell the ants back for a profit, before it was exposed as a ponzi scheme in 2007.
