Let's just say you have a nanmu tree at home. Without Jin Sinan, Nanmu would only produce gold thread in a certain year, but in Qing Dynasty, gold thread could only be used as a tribute. Therefore, the price with and without gold thread is different, and the price with more gold thread is very different from that without gold thread. Now the price of nanmu without gold thread should be 5,000-8,000 yuan, and Jin Sinan with a tribute of 8,000 yuan should be able to buy a small sculpture.
