The minister of Rites would receive the edict in Taihedian (Hall of supreme Harmony), where the Emperor was holding his court. The Minister would then carry the decree on a yunpan (tray of cloud), and withdraw from the Hall via Taihemen (Gate of Supreme Harmony).

1) The minister would put the tray in a miniature longting (dragon pavilion), beneath a yellow umbrella and carry it via Wumen(Meridian Gate),Tiananmen Gate tower.
2) A courtier would be invested to proclaim the edict. The civil and military officials lining both sides of the gateway beneath the tower would prostrate themselves in the direction of the emperor in waiting for the decree to the proclaimed.
3) The courtier would then put the edict in a phoenix-shaped wooden box and lower it from the tower by means of a silk cord. The document would finally be carried in a similar tray of cloud under a yellow umbrella to the Ministry of Rites.
4) The edict, copied on yellow paper, would be made known to the whole country.
Such a process was historically recorded as Imperial Edict Issued by Golden Phoenix.
During the Qing and Ming dynasties Tiananmen was the most important passage. It was this gate that the Emperor and his retinue would go through on their way to the altars for ritual and religious activities.
