Is chess patented in Korea? Did China apply for cultural heritage protection? Is this chess game very different from the other one in terms of rules and composition? Could it be piracy?

2. In 2006, China Chess was included in the intangible cultural heritage of Beijing.

Although their rules are somewhat similar, there are obviously more differences. You can neither say that they are very different nor that they are very similar.

This kind of thing can't be said to be pirated. You can't say that "football and basketball are a group of people who want to send the ball to a specific place, so there may be plagiarism between them"? I don't know why you ask, because most people don't think that "a game of chess in China may be pirated"
