A leading Chinese tea drink chain has stopped selling recently launched products and merchandise featuring images of ceramic Luohan sculptures after allegations it was engaging in an act of commercial promotion in the name of Buddhism, which is against the law in China.

On Nov 28, Hey Tea released co-branded tea and merchandise with the Jingdezhen China Ceramics Museum in Jiangxi province. The collaboration, named Hey Buddha, featured three of the ceramic sculptures exhibited at the museum depicting the 18 Arhats, or Luohan in Chinese, from Buddhism.

Among them, the Thinking Luohan gained internet notoriety earlier this year after memes of a photo of it with the added text "speechless" went viral. Taming Tiger Luohan and Happy Luohan from the series also went viral, becoming the other two designs from the collaboration.

Hey Tea printed the images of the three Luohan ceramic sculptures on the special paper cups designed for the tea lattes in the series. Other merchandise included fridge magnets. With the younger generation increasingly interested in Buddhist culture, the collaboration quickly became a hit on social media.

On Friday, the Shenzhen Ethnic and Religious Affairs Bureau talked with the tea drink chain, which is headquartered in Shenzhen, Guangdong province, and informed the company that the collaboration could be seen as an act of commercial promotion in the name of religion, which is against China's Regulation on Religious Affairs, thepaper.cn reported on Sunday evening.

A directive introduced in 2017 to specifically tackle the issue of commercialization of Buddhism and Taoism, also prohibited commercial promotion in the name of Buddhism and Taoism.

A bureau staff member said Hay Tea had been very cooperative. By Sunday, it had removed all paper cups and merchandise from the collaboration from its outlets across the nation.

Hey Tea's alleged violation of regulations on religious affairs became one of the most discussed topics on social media on Monday.

Li Yanqin, who bought a tea latte from the collaboration said she thought the paper cup with a Thinking Luohan was just for a laugh at first, but then she found herself in an awkward situation when she finished the drink.

"I don't know if I should throw away the cup or not," she said. "I am not a follower of Buddhism, but I don't think it's a respectable thing to just toss the cup in the bin because there is an image of Luohan on it. Now, I still have it on my desk."

She said companies should be respectful to all religions and their followers.

But some people said Hey Tea only used images of ceramic Luohan sculptures, which were just artworks from the perspective of many people, meaning the allegation could be flawed.
