As you can see, whether it is the Mongolian Archer, the Mongolian cavalry Archer, or the camel cavalry Archer of the Abbasid Dynasty, when upgrading to era 4, the weapons of these units that use the recursive bow in the game will become a golden bow.
However, only the weapons of Chinese archers remain unchanged from beginning to end, which is undoubtedly uncoordinated. The ordinary bow does not match the golden helmet archers of era 4, so please fix this bug and make the units using recursive bow in the game upgrade consistently.
