Closing Alignment and Straightness of the Tuan Shan: Making the Fan Close Clean Into a Neat Stack

A well-made tuan shan closes clean — all ribs come together into a straight, even stack, and the pivot sits true. Crooked closing comes from misaligned pivot holes or uneven rib thickness. Precise assembly of the pivot and ribs is what makes a fan close neatly and feel finished in the hand.

The Scenario: Three challenges in closing

Clean closing faces three challenges:

Pain Points

• Misaligned pivot holes make the fan close crooked or bind;
• Uneven rib thickness leaves gaps and a messy stack when closed;
• A true, smooth closing motion is the sign of careful assembly and finish.

The Solution: Three closing solutions

Precise assembly offers three solutions:

1. True pivot alignment Align the pivot and holes precisely so the fan rotates and closes true.

2. Even rib thickness Keep rib thickness even so the closed stack is straight and gap-free.

3. Smooth closing motion Fit and finish the pivot so the fan opens and closes with a smooth, even motion.

The Result: A fan that closes clean

With these solutions, the fan closes into a straight, even stack and feels finished. Clean closing is the mark of a carefully made tuan shan.
