In east China's Zhejiang Province, inventer Yang Zongfu was busy producing his version of arks, a type of survival capsule after the apocalypse, which sold at between 1.5 million yuan (238,095 U.S. dollars) and 5 million yuan. He received 26 orders.
"Have you bought the ark tickets?" became a popular greeting for students at Jianxi Agricultural University instead of the traditional Chinese saying "Have you had your meal?"
Fang Zhenwu, an instructor with the university said many students also used "Doomsday" as an opportunity to confess love.
Online home appliance vendors also took advantage of the "Doomsday" craze to promote sales by offering larger discounts. Book stores had a sales boom on reading material about survival skills in the wild. The demand for camping tools, including candles, survival packs, portable sleeping bags, surged in the last two weeks.
"We are busy working and living under pressure, and our lives need some sort of entertainment," said Pan Feng, "The Doomsday tale provides us with a chance to have a bit of fun."
