Stunning display piece

I am not usually into building blocks, but the architecture of Chongqing fascinated me. This kit did not disappoint. The tiered design is cleverly engineered. It serves as a great conversation starter in my living room.

An Incredible Architectural Challenge

This set is absolutely massive and stunning. The detail on the Hongya Cave structure is impressive, capturing the layered look of the real landmark. It took me about three weeks of evening building to complete, but every moment was enjoyable. The instructions are clear, though you definitely need a large table space.

Beautiful but time-consuming

The final model looks fantastic on my shelf. The color palette is accurate to the traditional style. I deducted one star only because sorting the 10,000+ pieces took forever. Make sure you have good lighting and plenty of storage bags before you start.

Worth every penny

For the price during the loss leader sale, this is an absolute steal. You get over 10k pieces of high-quality plastic. The repetitive nature of building the multiple levels is actually quite meditative. Highly recommended for patience and precision lovers.

Great quality, missing one small part

The bricks fit together smoothly with nice clutch power. Unfortunately, I was missing two tiny 1x1 plates in bag #45. I contacted support, and they sent replacements quickly, so no major issue. The build experience itself is top-notch.

Perfect gift for advanced builders

Bought this for my son who loves complex puzzles. He was thrilled by the scale and complexity. The structural integrity is surprisingly good once finished; it doesn't feel fragile despite its size. Great value for the piece count during this sale.

5 FAQ

Q: Are the stickers pre-applied or do I have to apply them myself?

A: All decorative elements are molded directly into the bricks or use printed pieces; there are no stickers to apply in this specific set, which ensures a cleaner look.

A: Absolutely. The ABS plastic bricks are designed to be snapped apart and reconnected multiple times without losing their grip strength, making corrections easy.

Q: How long does it typically take an average adult to finish this model?

A: Most customers report completion times between 20 to 35 hours, depending on experience level and how much time is dedicated per session.

Q: Is the instruction manual available in English?
