The spirit of playing cards is to come as long as someone calls you, no matter what the situation, as long as there is a bureau to call you. Because when playing cards, you must greet people first, and shouting is shouting. Players just don't pick people, places or conditions. They can get up early, stay up all night, forget all their troubles and worries, and enter the realm of "no one". The spirit of playing cards is broad-minded.
