it’s definitely a thing in civil law jurisdictions, so we shouldn’t be surprised to find it in Taiwan. The main difference is not the law per se but the cultural standard of what’s acceptable and unacceptable.

Insult is reserved to countries of civil law but a similar behavior in public can be considered public disorder in common law, especially in that of the United Kingdom[7] and former colonies of the British Empire after 1776.[8] The difference is that in civil law there is a personal target and the damaged legal good is their honor but in common law the public is targeted and the damaged legal good is the public order. The unlikeness persists also in public insults of civil law.
