Who is the lawyer Lao Zhang starring?

The plot analysis of prosecution witness: Sir Wilfri, a famous British lawyer, has just finished heart surgery. The doctor specifically told him to rest after returning home and not to participate in the defense of criminal cases. When Sir Jazz came home, his old friend came to visit Mr. Wall. It turned out that Mr. Wall was involved in a murder case. Jazz didn't want to take the case for physical reasons at first, but he changed his mind when he saw the cigar on his friend's chest.

In the name of talking about the case, Mr. Wang smoked a cigar in the studio and asked the case at will. Mr. Wall was very frank and passed the Jazz's lens test, so Jazz judged from experience that Mr. Wall was not lying. However, at this time, the jazz did not want to take over the case himself, so he recommended Moore to Mr. Wall.

As the case progressed, Mr. Wall was listed as the main suspect, so the police took him away from Jazz's studio. Before being taken away by the police, Mr. Wall told Mr. Wang to remember to contact his wife, and he was full of confidence in her.

Jazz found something strange when he talked to Mr. Wall's wife. He suspected that the relationship between husband and wife was not as sweet as Mr. Wall described, which made Sir Willing to take over Mr. Wall's case himself. But the price is that after the case is over, Jazz will go to Bermuda to recuperate.
