In the past years, I have seen the rising sun, I have seen the sunset, I have seen the beauty of the flowers, and I have also seen the sadness of the flowers. The footsteps of time are always in a pace that we cannot perceive. The shadow of reincarnation is always in the corners around us. Sadness, a trace of entanglement will entangle us, can't open the confused eyes, can't shake off is the unforgettable feelings.
