China's online businesses are profiting from a technical glitch at Friday's Sochi Olympics opening ceremony through T-shirt sales.

After one of the five Olympic rings failed to light up during the ceremony on Friday, vendors started selling T-shirts, sweaters, and tops featuring a "four-ring" version of the Olympics symbol.

The merchandise was available on Taobao.com, China's eBay, starting on Saturday, just one day after the opening ceremony. Prices ranged from 18 yuan (2.97 U.S. dollars) to 168 yuan.

As of Monday noon, 65 items with the four-ring design were displayed on the website. Sales for the most-bought design hit 58 items over the past two days.

Netizens said the four-ring design reflected "beauty with flaw," and considered the quick response of vendors a sign of Chinese businesses' ability to find creative ideas in world events.
