1, avoid contact with high temperature when wearing cinnabar, because cinnabar will exert toxicity at high temperature, thus affecting human health. Cinnabar can't be worn with silver jewelry. Mercury sulfide in cinnabar will react with silver ions, resulting in black spots on the surface of silver jewelry. Note that cinnabar is fragile and collision should be avoided.

2. Men should avoid high temperature and strong direct sunlight when wearing cinnabar, because cinnabar contains mercury, which will produce and volatilize toxicity at 386. Thus affecting human health, and high temperature will also make cinnabar discolored.

3. Men can't put cinnabar and silver ornaments together or wear them, because the main component of cinnabar is mercury sulfide, which will react with silver ions to generate silver sulfide. Silver sulfide will cause black spots on silver jewelry, which is not easy to clean.
