Fire Nation Colony Spa: Incense Burner
At the spa, at the beginning of season two, we see two incense burners in the background. Incense is not only burned at temples for worship but also has medicinal uses.
Incense in China is traditionally used in a wide range of Chinese cultural activities including, religious ceremonies, ancestor veneration, traditional medicine, and in daily life. Known as xiang 香 (literally “fragrance”), incense was used by the Chinese cultures starting from Neolithic times with it coming to greater prominence starting from the Xia, Shang, and Zhou dynasties.
