i find NDP fireworks is just like firing gpmg.
Spain's fireworks only the orbs with the belt looks nice. also like gpmg, maybe slower than NDP's.
China's fireworks is great, 3 distint height, stopping inbetween to allow the smoke at the medium and highest height to be blown away, unfortunately wind not strong enough, but so beat the previous 2 teams. the fireworks also looks better, got heart shape, flower shape etc. the low level fireworks is also better design than the rest (as a viewer, not taking photos).
