The Martial Arts in the Great Xia Dynasty have a long history. The earliest periods of martial arts are unfathomable, but be it in official history, extrapolation, or mythical legends, related records can still be traced back to the earliest periods.
Martial Arts seem to have appeared alongside the civilization of the Great Xia Dynasty, or even before written records were made.
After all, in ancient times, with undeveloped technology, individuals' combat capabilities played a decisive role.
Moreover, medicine and martial arts were inseparable. Before the appearance of writing, the ancestors of the Great Xia Dynasty explored how to cure diseases and heal injuries, so it's possible that martial arts existed even before writing did.
The tradition of martial arts in the Great Xia Dynasty stretches back so far that it is not known how many years it has been passed down. Even the same secret script could have given rise to numerous sects over the years.
