hóngkuài) is a species of Chamaecyparis, endemic to Taiwan, where it grows in the central mountains at moderate to high altitudes of 1000–2900 m. It is threatened by habitat loss and over-cutting for its valuable timber.

The juvenile leaves, found on young seedlings, are needle-like, 4–8 mm long, soft and glaucous bluish-green.

[2] It is most closely related to the Japanese Chamaecyparis pisifera (sawara cypress), which differs in smaller globose cones 4–8 mm long with 6–10 scales.

[2] The wood is soft, very resistant to decay, and strongly scented; it is highly valued in traditional Taiwanese building, particularly for temples and shrines.

A small number of the oldest and largest specimens are protected as national monuments, but much of the general population of the species still remains unprotected.
