Since the bidding ranking was exposed by CCTV, Baidu has experienced an unprecedented trust crisis. Entering 2009, Baidu took a series of actions and was eager to turn the situation around. Robin Li probably believed that doing charity work was the best way to reverse the corporate image, so he shouted out the slogan: "The more in economic crisis, the more enterprises should talk about responsibility, the more they should do charity." But at the end of the day, he still understood: the worse the global economy is, the more you need to learn to be frugal; often charity can only bring fame, not profit. So a way had to be found to spend the least money for the most profitable thing. After much thought, it seemed that the elderly were easier to persuade, and thus the great "charity website" of Baidu Senior Search was born.
