What happened after Zhang started selling by video?

Zhang Wei grows apples on a hillside in Shaanxi province, but his income no longer comes from the orchard alone. Three years ago he began to sell his fruit through live video on his phone. Viewers watch him pick apples, ask questions and place orders, which are delivered across the country within two days. His sales have tripled, and he now employs six neighbours to pack boxes. Zhang says the most difficult part was not learning the technology but speaking confidently to a camera. He still spends every morning in the orchard, because, in his words, customers can taste the difference when the fruit is picked fresh.
