How many times has the pianist's mood changed?

Generally speaking, there are four changes. The emotional changes of the two people have sublimated the theme of the film again and again, mainly the change of white driver Tony's attitude towards the black pianist Tang.

First of all, the early two people hated each other and hated each other. At the beginning of the film, Tony threw the water cup drunk by the black man into the trash can, and as his wife said something mocking the black man, it can be seen that Tony has serious racial discrimination and he hates the black man. So even if he is a pianist and Tang is a driver, he still looks down on the black man from the bottom of his heart. He can be said to be very rude to Don. He ate the bread given by his wife without asking Don, and got off the bus and took his wallet, all of which can show Tony's prejudice against blacks.

The second change happened when Tony listened to Tang's piano performance. He called Tang a pianist in his wife's heart. It can be seen that Tony was deeply impressed by Tang's skills and respected his profession. He still did not abandon his prejudice against Tang himself.

The third time, the farther south you go, the more unfair treatment you get. In order to protect Don, Tony beat the police and was arrested at the police station. After getting off the bus, Tony realized that they were actually the same kind of people. In his letter to his wife, Tony offered to polish Don. Tony officially accepted Don from the bottom of his heart.

For the fourth time, Tang canceled his last concert and returned to the north. At Tony's invitation, Don went to Tony's home, and both of them were relieved at that moment. Really became friends.
