quote / unquote

When we relate something as told by another, however, as there already quote marks in the passage, how to write the words "Quote" and "Unquote" around the overall passage and left it in the first person? Take the following story for example. Is it acceptable?

Here are some events which challenge us to contemplate on what kind of next generation we are seeking to develop through education.

Huang Chun-ming, a senior Taiwanese literary figure and teacher, recently had something happen to him which upset him and which he talked about.

“Once I took the train back to Taipei from Ilan. Halfway, at the Juifang station, a group of high school students got on the car. Crowding outside the toilet, they were noisily laughing and joking as if there were no one else on the train. As I came out of the lavatory, while the train was making a turn, I accidentally bumped into one of the students."

"‘What the f*ck are you doing?’ He was very upset."
"I said, ‘Sorry, the train is shaking badly.’"

"He looked at me and retorted, ‘Anyway, you’re condemned to die!’ The young man’s unpleasant attitude and rough remarks upset me. After I got home, I told my wife about the incident. How come these Taiwanese kids are becoming so rude and unreasonable? Even if I am going to die, he didn't have to say that.”
