5. Good reviews can be cost-free

When Xiaomi rolled out its first project MIUI, Lei Jun asked Li Wanqiang to attract its first one million users at no cost. Focus on good reviews is the only way. Customers need to voluntarily boast about your product and recommend it to others.

Later when Xiaomi launched its smartphone, the company had no advertisement budget, and turned to new media as its sole promoting channel.
