Why didn't the director let the actress be on camera before the film started?

This rule was handed down from the early troupe. At that time, Dan Jiao was not allowed to take a suitcase, but many artists in Hong Kong were born and passed down in the pear garden. Later, the mainland also used it.

There is also a saying that girls will lose (wet) focus when sitting in the lens box. Traditionally, boys are yang and girls are yin, so many older photographers won't let girls touch photographic equipment, and they don't know if it's true or not.

Precautions:

There is a necessary ceremony when the film starts, that is, burning incense. Producers and directors usually take the lead in burning incense, praying for a smooth shooting, and covering the camera with red cloth. Sometimes you need pig's head meat, fruit, tobacco and alcohol.

In fact, these ceremonies can't be regarded as superstitions, because there are many unknowns in the filming process, and in most cases, they are for peace of mind and gradually form a culture. Of course, the formation of this culture is also due to some unspeakable things. For example, some people say that when shooting scenes such as temples with cameras, they often look back and see nothing.
