Were ancient Koreans (Koreans) good at fighting?

Ancient Koreans were not good at fighting, but they were good at serving big shots. They are very smooth!

Historically, the Korean peninsula has been able to stand up for the three countries for a long time, not because the soldiers of the three countries are brave, but because the diplomatic envoys of the three countries tried their best to please the Central Plains dynasty and prepare to support which country. The final decision is still the three countries themselves. After reunifying the peninsula, the victors still kept a low profile and expressed their willingness to continue to submit to the Central Plains Dynasty and increase their tribute.
