1. Mobilize Jeff. Jeff's transfer is mainly divided into two categories, one is to transfer soldiers, and the other is to replace local officials. This kind of Jeff was called the bronze tiger symbol and the bamboo messenger symbol in the Han Dynasty. The bronze tiger logo is cast into the shape of a crouching tiger, which is divided into two parts and combined with tenons. The symbol on the left is sent to the chief or leading general, and the symbol on the right is stored in the center. The central government mobilized the county chief and the army, and sent people to carry the right and left symbols as tokens to convey orders. The bamboo ambassador is made of bamboo, which has the same purpose as the bronze charm, but the situation is not as urgent as the bronze charm. After Wei and Jin Dynasties, this system was basically used, except that the central government left the left half and awarded the right half.
2. Send Jeff by post. Jeff postal delivery is a kind of letter that delivers orders through the post office. Jeff is mainly divided into two categories: one is ordinary mail, and the other is special mail. Ordinary postal delivery is a voucher for couriers and officials to use post stations, horses and chariots, and accommodation. For example, the Wooden Biography of the Han Dynasty is divided into two parts with a letter signed by the imperial doctor, indicating the priority of affairs and the level of use of horses and chariots. Half of them are distributed to users, and the other half are kept in the Ministry of Internal Affairs for inspection. Half of the users registered for each post. In addition to the documents delivered by ordinary post, express post also has special and obvious signs to show its importance and urgency.
3. Ambassador Jeff. Ambassador Jeff is the token and symbol held by the imperial envoys sent by the emperor. Jeff, who holds the envoy, can represent the emperor and the country. All previous dynasties made a relatively complete management system for Jeff's distribution, use and storage as far as possible, so as to ensure that imperial edicts, decrees and documents were not tampered with and leaked in the process of inheritance and operation, which reflected the rigor of paperwork at that time. At the same time, as an important document, Jeff is also a symbol of power. Therefore, all previous dynasties had strict management systems in storage, use, distribution and production.
