Yeon (輦) is the palanquin mounted by the king mainly for the royal processions to distant places outside the court. It consists of a roof, a carriage, and poles for carrying, and overall imitates the structure of a house.

The carriage has a round pillar with a dragon design at each corner, supplementary square pillars in between, and railings around the lower half. Its body is lacquered in red and the railings are decorated with drawings of mythical animals in gold. The connections between the wooden parts are strengthened with silver-inlayed clamps.

Silk blinds and awnings were attached on the four sides of the palanquin body and these can be propped up or drawn down. The phoenix heads decorating the corners of the roof each hold a tassel with decorative knots, and gilt dragon heads cap the four ends of the horizontal poles.
