Shangyun Pavilion and Lingxiao Pavilion are two agencies established within Tuo Shi, where power is concentrated. Regardless of the size of matters, they are recorded in Shangyun Pavilion and Lingxiao Pavilion, and must be approved by these pavilions to be implemented. It's akin to not having the approval of a major boss; you don't have the right to do anything.
Initially, Tuo Shi established Shangyun Pavilion to manage all affairs of Tuo Shi. However, to prevent Shangyun Pavilion from becoming too dominant, Lingxiao Pavilion was specifically set up to restrain Shangyun Pavilion, allowing the two departments to maintain a balance.
