Iron is strong, but the fire can melt
The fire was strong, but water can extinguish
The water is strong, but the sun can beat him
The sun was strong, but the clouds can be prevented
The cloud is strong, but the wind can move it
The wind was strong, but humans are capable of holding
Man is strong, but fear could weaken
The strongest is the kindness and love, he will not disappear after death, will remain.
