A young person's loss of life has turned into a meaningful lesson for China's whole e-service industry.

For over a week now, the largest Chinese search engine Baidu.com has been a target of public questioning and debate for its possible role in the death of Wei Zexi, a university student, who paid dearly for a cancer treatment that apparently didn't help prolong his life after allegedly being misled by promotional information from a hospital he found during an online search on Baidu.

Government investigators were dispatched to look into the roles of the search engine and the hospital in question.
