What are the origins of the Watergate Ritual?

The Origin of the Watergate Ceremony: In the olden days, people used to make a passageway shaped like a "gate" with a sword or a stick in their arms, and then they would let people walk through it as a sign of blessing and remembrance. Later, with the development of society, the scale of things to be commemorated expanded, such as airplanes, ships and so on. "Saber arch" or "arm arch" and other forms have not been able to meet the needs of reality, so it gradually evolved with fire engines in the air spraying water, so as to build a "water gate" form. The form, to express the celebration and blessing.

In the civil aviation industry, it is common for planes to pass through water gates to commemorate retired senior pilots, air traffic controllers, or an airline's first or last flight from an airport, or other high-profile events.
