At 17:09 last Saturday afternoon, when there was half an hour before off duty, I received a call from Zhejiang (0571-85028080) while attending a meeting. Maybe the girl in the call did not speak clearly or maybe I didn't listen carefully. At first, I thought it was another call from Alibaba's staff asking me to join in the trustworthy network. Later, when I heard advertising space, I suddenly realized that it was not Alibaba but its wife Ali Mama.
