In the Lijiang Tower of the game map, players can see three astronauts after entering the gate of the left attack point. After turning on the high special effects, they can see that Blizzard has put a wreath under the spacesuit and put Hongyu's name on the famous brand of the spacesuit. Players can also see a line: "Heroes are immortal". This is a special egg set up by Blizzard to commemorate the brave college student Wu Hongyu.
