The chitin powder used to create feng shui had two joints cracked

Does the questioner want to ask "What is the reason for the cracking of the two joints of chitin powder used to create Feng Shui"? The temperature is too high and the material is defective.

1. Chitin powder requires a certain temperature when curing. If the temperature is too high, it will easily lead to joint cracking.

2. The chitin powder used is of poor quality or is mixed with other impurities, which can easily lead to joint cracking.
