Chapter 127 The Watch Identifies the Murderer
The businessman Bai Xiancheng who got rich suddenly encountered a lot of trouble, because after he found out that his wife was having an affair, he hired someone to beat the wife severely and even broke the man's left leg.

Just when Bai Xiancheng was feeling very relieved, the thugs he hired ran to him like a bereaved dog and told him that the person who was beaten was actually the younger brother of a local gang leader, and he had already organized people to hunt him down.After speaking, the thugs fled to the field.

Bai Xiancheng thought it was a big disaster, because he knew how powerful the other party was.So, he found a middleman to make peace with the other party, willing to spend money to eliminate the disaster.At around 8 o'clock in the evening, two "guests" came to the guest room of a large hotel where Bai Xiancheng was staying.Unexpectedly, about half an hour later, perhaps a fierce quarrel broke out in the negotiations, and gunshots came from the guest room.The waiter ran over quickly, and the two "guests" were running out of the guest room to escape from the hotel. The waiter didn't dare to stop them, so he entered the room to observe.Bai Xiancheng stared wide-eyed in horror, was shot in the neck, and blood gushed out. He held the waiter's hand tightly and said only one sentence: "Murderer, 20:47." Then he fell to the ground and died.

After the criminal police arrived at the scene, they quickly found the two suspects based on the physical characteristics of the two "guests" provided by the waiter.However, the two suspects accused each other of killing Bai Xiancheng, and there were no traces of the two on the pistols found at the scene.

Therefore, the criminal police checked the different watches of the two men, thus identifying the murderer and forcing him to confess.What watch revealed the murderer?
【答案】因为死者说是20点47分，所以带数字式手表的人是凶手，若看到表盘式手表的一定会说8点3刻或8点50分。
