--FILE--Chinese workers process glass covers for electronic products at the plant of Lens Technology in Langli town, Changsha city, central China's Hunan province, 12 March 2015. Zhou Qunfei, chairwoman of Lens Technology, has ousted Chan Laiwa, founder of Beijing Red Sandalwood Cultural Foundation as the wealthiest woman in China. The recently-listed Lens Technology saw its shares surge by the daily limit to 70.98 yuan ($11.44) per share on Monday, boosting the value of Zhou's 592-million-share holding to 42.02 billion yuan. Chan was earlier named China's richest woman, with a total asset of $6.1 billion, equivalent to 37.86 billion yuan, according to a global billionaire list by Forbes released on March 3. Lens Technology debuted on the Growth Enterprise Market board in Shenzhen on March 18, with an offer price of 22.99 yuan per share. The company makes glass covers for various consumer electronic products such as smartphones, computers and cameras. Its combined sales to Apple Inc and Samsung Electronics Co made up more than 70 percent of the company's sales revenue between 2012 and 2014. It is also a glass provider for Apple's newly launched Apple Watch earlier this month.
