Mango guru spreads farming techniques

Are you doing well if you own four houses and a pickup? Many urban workers might say yes, but the answer is different for farmer Mo Wenzhen, 55, of the Zhuang ethnic group in Baise, Guangxi.

"I don't think I am wealthy," Mo said with a broad grin.

His interpretation of wealth goes beyond individual finances to sharing his expertise with other farmers so they can prosper together.
