What is the content of Unicom's long-double-card youth friend activity?

The activity time of Unicom's young friends with long dual cards is from July 26th to June 26th, and from March 30th, 20 18. After receiving the traffic, the old Unicom users will click "Share More Traffic" to generate an exclusive invitation link and share it with their friends. Friends will apply for Qingdao Changshuang Card through the exclusive invitation link shared by the inviter. Every time the inviter successfully invites 1 friends to complete the activation of Tsingtao Brewery Changshuang Card and recharge 50 yuan and above for the first time, they can get 1GB national traffic. This activity is now over, I hope you will continue to pay attention to other offers.
