思路清晰角度贴地务虚的话不必说太多母亲とが话しています免费甚至不需要对苦难和感恩情绪的渲染Just tell people what it was like before, what has been changed, who invested the money, led by whom, how did wisdom show and inspire the whole changing process, how people living there feel before and after, and what has been done to maintain the change. Very, very inspiring for telling a story of "development"
