For Gao Junping, an unexpected visit to his home last February by then-vice-premier Li Keqiang helped his family realize a dream of generations - moving out of a run-down residence in a poverty-stricken shantytown.

"My father lived here. I got married and lived here, and so did my son. I don't want my grandson to continue living here," Gao said.

His grandson, Gao Yubo, now 6, created a public stir when he emerged from a closet with no trousers during Li's televised visit last year.
