"Lotus" refers to a purse on a person, and "official" refers to some staff in the casino, because people who come to the casino will think that these lotus officials can decide how many chips they get, so they are called "officials"; In English, the word "lotus official" has more meanings, some of which refer to his status as a businessman, dealer or some kind of actor.
There are a large number of casinos all over the world, such as Macau in China, which is our most familiar casino, and there are also very famous casinos abroad, such as Las Vegas.
Nowadays, with the rapid development of economy, the number of casinos has increased dramatically, and their distribution has gradually become widespread, such as in South Korea, Japan and the Philippines. It is conceivable that the demand for Dutch officials has also increased greatly, and the requirements for recruiting Dutch officials in each country and region are different. Some casinos need to come from the same nationality, while others don't.
