To combat the unattractive sadness felt en masse by the Chinese the Chinese government has arranged for people to stand in public places and smile at others. Statistically, it really means that there will be more happiness.
Best quote ever:
"We ask all the members to practice smiling at home," team-leader Xu Xiaohong told the paper. "We smile at the mirror to determine whether our smiles are acceptable. We not only smile with our mouths but also with our eyes."
With a technique as focused as that, emotional problems will be a thing of the past because as we know - if you look happy you are happy. That is all.
