The muzzle sprayer head is a full group equipment, the fog is extremely slight, it will be treacherous with the natural wind direction and wind speed, sometimes it will return lowly and hover, it shelters from the sprouting center, which like a fog rising from the horizon. It sometimes rises to the clouds just like a stream of thick smoke from the underground. Sometimes the fog color is dignified, sometimes it is smoky, just like mist and fog shrouding the whole fountain. Under the reflection of the sunshine in daytime, it is like the rainbow all over the sky. At night, it is against the colorful lights. The whole spraying gives off dreamlike poetry, it will let people stay for a long time.
