Photo shows fireworks in the shape of SPRING over the National Stadium during the opening ceremony of the Beijing 2022 Olympic Winter Games.

The fireworks show during the opening ceremony of the Beijing 2022 Olympic Winter Games followed the concept of simplicity and lasted for just about three minutes. The amount of ingredients used in the fireworks was only 10 percent of what was used during the Beijing 2008 Olympic Games. The special effects fireworks used this time were hi-tech micro-smoke fireworks containing non-toxic chemicals, making them environmentally friendly.
