Texts for other major religions are available online in China: The Taoist classic the Daodejing is for sale on JD, Taobao, and Amazon, and Buddhist sutras are available commercially.

The Quran was also sold online, perhaps reflecting Islam’s status as a faith practiced by minorities who sometimes enjoy more privileges than the majority ethnic Chinese population. The Quran is also available commercially in bookstores and, unlike the Bible, has the Chinese equivalent of an ISBN, a numeric book identifier.

Both Christianity and Islam, however, have come under heavy government pressure.

From 2014 to 2016, more than 1,500 crosses were removed from churches in one Chinese province with close ties to Mr. Xi. At the same time, the government has stepped up measures against what it sees as excessive public displays of the Islamic faith, such as men wearing long beards or women wearing headscarves, as well as shops and restaurants that do not sell pork products, tobacco or alcohol.

At the same time, government policy has encouraged faiths that it sees as more indigenized, for example by subsidizing Taoist music or folk religious pilgrimages. Mr. Xi has also spoken favorably about Buddhism, calling it integral to Chinese people’s cultural and spiritual life.

This overall approach to faith was reflected in a report issued Tuesday that shows the extent of the country’s religious revival. The previous report, in 1997, showed that China had 100 million followers of all of its officially sanctioned religions. The new report doubles the number.

Although other surveys show higher overall numbers, the new report is significant because it represents official recognition of China’s religious boom.

The report shows that most religions in China have been quickly increasing their reach. The number of Buddhist or Taoist believers was not counted because those faiths lack membership rolls, but their growth can be seen in the increasing number of temples — to 33,500 and 9,000 today from 13,000 and 1,500 in 1997.
