Turn on the cabinet lights (small lights at both ends of the cabinet). Don't underestimate light, it will give off heat.

It's amazing.

The light in the counter is very strong and the temperature is high, so jade ornaments cannot be preserved for a long time in this environment. Putting a glass of water is not only for beauty, but also to reduce the damage of light to jade and lower the temperature, because there are a lot of crystal water in gems and jade articles, but the crystal water is unstable and easy to be lost due to excessive heat and illumination. So put a glass of water to increase the humidity in the counter and make the jade look wet (which means "good texture" in jargon).

So in order to avoid the high temperature, a small glass of water will be put in it, and the water will evaporate quickly. .
