Why are there two 17 great treasure kings?

Karmapa, the King of Dabao Dharma, is the pioneer of reincarnation of the living Buddha, and only he certifies himself. Before every King Dabao dies, he will write a prophecy letter about the birthplace and parents of his next life, and then his disciples will follow this prophecy letter to find the newly reincarnated King Dabao. Karmapa Ujin Qinlieduoji, the 17th King of Dabao in life's core monuments, was found according to the prophetic letter of the 16th King of Dabao during his lifetime. As for the other one, it's fake, of course.

Moreover, there is nothing 16 given to him by King Dabao, and he will understand many things.

There is only one Wang Dabao, but there is no incarnation of body, language, heart and career.
