Besides the green card and the blue card, what other colors are there?

If you simply ask the color, the cards issued by different companies are all different colors.

Initially, only CITA Construction Industry Training Bureau issued a green card.

So everyone is used to calling it a green card.

But now many organizations/companies can issue green cards.

The following organizations/companies can issue green cards.

Blue card refers to the basic safety training course for cargo handling on board. Reference: labour/osh/mbstcw, I'm from Polytechnic University, and I'm Bai ga~

It's strange to see it on the construction site because of the small relationship. China Hongkong Human Resources Co., Ltd. cannot issue security cards.
