All those present sing the song 'All in One Heart' in front of the huge pin badge mosaic to celebrate the 20th anniversary of Hong Kong’s return to China.

Twenty Hong Kong organizations in Shanghai from different fields got together for the first time at the South Square of Xintiandi on June 24, 2017 to jointly host a celebration, marking the 20th anniversary of Hong Kong's return to China.

They completed a 27.24-square-meter puzzle with more than 15,000 pieces of closely linked love-shaped badges, which means 'Hong Kong Heart, China Heart, All in One Heart'. Certified by a Guinness notary attending the event, the puzzle has become a new Guinness world record for 'The Largest Pin Badge Mosaic'.

The Guinness world record attempt started from 12 p.m.
