The Taisui of the year occupies the fifth or fourth grade.
It oversees the Taisui of the month and the day and has the authority to patrol the four directions.
The title sounds imposing, and holding the position is equally so.
For instance, Gu Xiao, who was bestowed with the position of Tiger Year Taisui, would inspect the Divine Continent during the year of the Tiger, punishing mortals and demons who did not respect the Heavenly Court.
For the common folk, it's an intermittent boss to be feared and appeased with proper worship.
To the immortals of the Heavenly Court, however, the yearly Taisui doesn't have authority over them; at most, it's like a security team leader, who doesn't even have patrol rights every year,
The Immortal Registry Department, one of the subordinate departments of the Ministry of Personnel, is responsible for the selection, promotion, and dismissal of officials.
