Anyone involved in escorting valuables always prioritizes the protection of the silver coins, cargo, and even personal safety, so, they often hold the word "harmony" in high regard.
In normal interactions with the government, they naturally greet with smiles, and during the escort, if they unexpectedly encounter bandits, no matter how domineering the other party is, they must endure and maintain courtesy to prevent trouble from arising. Recklessly revealing weapons will only escalate the situation beyond control, resulting in the loss of both money and goods, and could even endanger lives. For this reason, those with fiery tempers and high spirits simply weren't cut out for the role of an escort master.
