The flower language of Lan Yue is loyalty, love and unswerving determination. Humans often compare it to love, because its flowering period has no end. Once it blooms, it lasts a lifetime. If you pick off its flower, it will grow back a day later. The flower is the original flower, but it seems that it is not. The blue flower will bloom brilliantly until it dies.
The same is true for the most beautiful human love. Once you fall in love, it lasts a lifetime.
