The film "Green Book" is not much like the previous foreign blockbusters, and does not follow the previous routine, but adopts narrative techniques to express the things that want to be transmitted to people. In this film, Tony and the musician Shirley have a lot of funny stories in the process of touring, and their relationship is envied.

The driver, Tony, is a very dashing freelance worker, who has done a lot of odd jobs, the company has closed down and then looked for a job again, the family is waiting for him to open his mouth to eat, he only has to work hard, and even bet with a fat man for fifty dollars to eat twenty-four hot dogs, which is crazy.
He mistakenly met Dr. Shirley, who is actually a well-known pianist of our time. However, he was bound by the identity of the black man, and he exuded charm all over his body, and even this discriminator Tony could not help but be deeply attracted by him, although at first Tony was very reluctant to be a driver for the black musician, but he still went to make a living.
Shirley, a black musician, was more determined to hire Tony after learning that he was a discriminator, and Tony was attracted by the hundred dollars a week. Along the way, Shirley and Tony became good friends, and an Italian and an African-American musician became friends.
During these two months together, Tony helps Shirley solve her difficulties, and Shirley helps Tony write love letters to his wife. A rough, untrimmed Italian resonates a lot with a noble, self-respecting but delicate black musician.
From the relationship between hiring and being hired, to becoming friends, this is the charm of personality, in Tony Shirley saw the side that made her envious, but never dared to show, and Tony was always impressed by Shirley's personality charm.
