What does the ending of Andy Lau Alan Tam's film The Supreme mean? Of course, all these factors may cause women to be temporarily unhappy or even disgusted, but I don't think it's necessary to leave sadly, right? But the friend upstairs, first of all, he clearly knew that his card was a straight flush, so Chen couldn't even make a little mistake at that time, and she was sure to win; Second, about seeing the gambler's nature clearly, you should know that she knows that he is a professional gambler, and this time Tan's gambling money was prepared by her.

What he wants is an opponent's show, not to continue gambling. Without Chen's help, he might not have done it. If Chen makes a mistake, if he doesn't show his cards, they will lose. I don't know if I made it clear. When Chen opened the card, he already knew that Yasen had cheated him. At that time, Chen did not blame Yasen. She should know Yasen's kindness. She finally chose to leave because of the killer's question: What are you going to tell your fiancee? Yasen's answer was "I'll keep it from her all my life", which broke Chen's heart Think about how much Chen trusted Yasen and put all his possessions on him, including his own hands, even though he thought it was stealing a plane. Yasen finally said that he would keep it from her for life. I feel the most touching scene in the film: the crab begged Yasen for the last time to help him gamble, and Yasen didn't want to go back to the rivers and lakes. The crab proposed to flip a coin, and Yasen chose the head. After the crab tossed the coin, Yasen said, "I changed it this time. I know you have two coins, one with a head on both sides and the other with words on both sides. I knew it. I just kept asking you. " The crab was speechless and put the coin in Yasen's hand to leave. Yasen opened his palm and saw a coin with heads on both sides. He got a fright! I think at that time, the crab's heart must be very painful, and his brother for many years will be completely lost. I remember the ugly smile of the crab. "You know, the sad thing for a liar is to be exposed face to face." It was the crab that made Arsene understand what loyalty was, so Arsene finally gave his life to avenge the crab. Life is full of friends like crabs.
