Wall Street Journal: Jack Ma, the Chinese billionaire and co-founder of e-commerce giant Alibaba, has quietly made a new acquisition: a 28,100-acre property boasting trout streams, woodlands and a maple-syrup operation in New York’s Adirondacks. Ma paid $23 million for the sprawling upstate New York property, which he bought principally for conservation purposes, but also plans to use as an occasional personal retreat.
