South Korea's "Unlimited Challenge" copyright has already been bought out by CCTV, and it is planned to be broadcast in June+10 this year. However, when the program of Dragon TV came out, it really played a good hand. Nowadays, variety shows, especially those with high similarity, whoever grabs the market first will be the winner. Together with these six big names, I believe the program can attract great attention. Whether it is plagiarism or not is difficult to draw a conclusion for the time being, just like flowers and teenagers are very similar to the sister flowers of the Korean version, but you can't say that people are plagiarized because they have made minor changes.
China is recognized as a cottage country, and I believe there is nothing to question. Variety shows have been like this for years. If you can't think of it, introduce it to Korea. If you can't, just imitate. Don't tell me that imitation is better than the real thing. For example, "Flowers and Teenagers" took the lead, and its popularity in China surpassed that of "Sister Flowers".
