Legal basis: The crime of opening a casino in the second paragraph of Article 303 of the Criminal Law of People's Republic of China (PRC) refers to the objective existence of gambling by gathering people, opening a casino or taking gambling as a business. Once the casino is officially opened and actually used by some people, it is deemed that this crime has been accomplished, regardless of whether the founder actually makes a profit. If the casino owner participates in gambling on his own and engages in gambling, he may consider merging this crime with gambling crime.
