This is Kunming largest collection of dozens of individual wood and wood product sellers. Therefore, there is no general contact information, and each shopkeeper keeps their own hours.
Overall good selection for creating basic "heavy / thick / bulky" furniture.
A reasonable choice of lumber that has improved over time. Fancy hardwoods like walnut, and mahogany are in abundance. There are some plywood and rubber-wood boards available. There are also some kiln dried imported softwoods and merbao available. Some of the lumber is very green, so look for the kiln dried if you need stable timbers.
