In the age of paid knowledge, ca
Knowledge of paied is replacing shared, become the new developing trendency.

We get resources mainly by Baidu ago, it's the primary choose of us.Because it was named as the China's google. So we choose to believe it because of it's reputation.

With the competitive ranking mechanism's developing, Baidu is more and more doubtful for people.I have read some articles which are complain that.

I gradually find that it's difficult to look for what we really need, even too much advertisement bring trouble to our life. Too much useless information or too many unwanted calls make us annoyed. If we want to get some resources, we need to register our information and then spend money to buy, there are no free knowledge.

"Knowledge is priceless", it's doubtful!
