Alibaba’s billionaire founder resurfaced as he spoke to 100 rural teachers through a video call, three months after his last public appearance in October, sending the e-commerce firm’s shares up more than 8% in Hong Kong.

A recording of the call was first posted on a news portal backed by the government of Zhejiang, the eastern province where Alibaba is headquartered, and the video was verified by an Alibaba spokesperson.
