Have you ever met someone who spoke Chinese on the streets of Japan, and was scolded loudly by an old lady, but still didn't understand what he said? What should you do if you meet him again?

I met a group of young people from Taiwan Province Province or Hongkong who were talking loudly on the tram. An old Japanese lady said they didn't understand, but they were indifferent. . . It's noisy in the tram. . That's why they are wrong, because Japanese rarely make such a loud noise on trams. If the old man doesn't like it, he should say it. I don't think these students are doing well. When they arrive in other countries, they should observe order and not make noise in public places. The solution is to stop arguing and keep quiet. . . What did you say?/Sorry? Do you still want to argue with the old lady? If there is a mistake, we must correct it. Never disgrace the people of China. We have a bad impression of China people. .
