In addition, the master-servant relationship was fixed due to an influence of Confucianism, and when a vassal gave up his master and left the place, the master sent to other daimyo a letter called 'Hokokamae' to close the door in order to serve another daimyo.
また、儒教の影響で主従関係が固定化され、家臣が主君を見限って出奔した場合は、他の大名に「奉公構」を廻して再仕官の道を閉ざすことも行われた。
