Liu Hongjun has spent the past year perfecting his family's recipe for rice wine, and says there is nothing else like it on the market. Fan Zhen reports.

Liu Hongjun loves sharing. He takes part in marathons to share his passion for running with thousands of others. He raises money to buy computers for poor children to spread his love of knowledge. Recently the software engineer decided to share another thing, the traditional handmade rice wine of his family. It had never occurred to Liu to make rice wine until one year ago when his wife gave birth. His mother came to Beijing and made rice wine to help her daughter-in-law produce breast milk. He used the extra wine to treat his friends at dinners and it became so popular that a lot of them came back for more.

"Why not learn to make it myself since my friends enjoy it?" he asked himself.
