With 12 hours before the opening ceremony of the Universiade, the mascot UU and the little actor who was a solo performer at the opening ceremony suddenly disappeared at the same time, and three special envoys of the Universiade with stunts immediately began a big search in the city. It turned out that UU, who has the super power of time and space, felt the drift bottle coming and took the little girl to see it. Three Universiade messengers finally found UU and the little girl at the seaside. They flew over Shenzhen with UU and arrived at the main venue of the opening ceremony on time. Open this mysterious drift bottle, which contains a congratulatory letter stamped with postmarks from all over the world. The theme slogan "Start here" is written on each postmark in the local language. Finally, these postmarks with the blessings of college students from all over the world flew into the air, forming a radiant Universiade emblem. At this time, fireworks were colorful and the Universiade was grandly opened.
