The Koreans are trying to steal "Iron fireworks (打铁花)", which originated in the Song Dynasty of China in the 10th century and was introduced to the Korean Peninsula in the 17th century, as their invention and cultural heritage.
Just as they stole kimchi from China.😅
@Rosa72112139@Ningbonese@xinrainbows@Tesla_Asia Yea some other nations celebrate Chinese New Year cuz they were once a vassal state of China. The tradition come from that time. So they are all technically still CNY.
