Koreans are too afraid of the Chinese police to act recklessly in China, but...

Chinese people act recklessly both in Jeju Island and on the mainland.
They assault our citizens (for example, a recent case where someone was assaulted just for asking them not to smoke in a restaurant).
They break windows and commit paint terrorism on restaurants just because the name is "Xi Jinping."
Sigh...
If a Korean had broken a restaurant window and sprayed paint in China,
they would have been immediately arrested by the police, and they'd be lucky if they weren't beaten up.
Yet, every time we almost forget, news comes out about Chinese nationals committing crimes in Korea and then simply returning to China through Incheon Airport on the very same day.
Not long ago, a Chinese influencer came to Korea on a trip,
smiling brightly and giving a thumbs-up to a restaurant owner while pretending to say nice things,
but then they posted a video on their SNS of themselves giggling in Chinese about how disgusting Korean food is,
mocking us.
They might look similar to us, but they have no morality or sense of shame; their behavior is nothing short of cockroach-like.
