The meaning of declaring a name is indifferent, quiet, warm, brave and rich. The word Xuan originally meant warmth, but in dialect it meant looseness and softness. Liu Junkuan's breakup theory says that if you are warm and depressed, you will become a cold valley. Later, it was derived from Xuanteng, which is sunny and peaceful, quiet and indifferent, meaning gentle and calm, peaceful and happy, harmonious and beautiful.
