Where the 14^th FINA World Swimming Championship (25 m) is now in full swing, a mind-blowing display of sci-tech elements becomes an attraction, which is a new presentation as Hangzhou is under way to be the first city nationally with digital economy.

One more attraction is two robots named “YOUYOU” at the entry and exit of “Lotus”.
