Rong Qiu answered honestly, "He wanted me to raise you and let you be happy... and not only that but he wanted his body to be burned after he died and he pleaded us to scatter his ashes to the ocean so that he could follow you wherever you go through the wind..."
This was indeed what the real Uncle Qiu said a few days his memory was being erased. He remembered those memories clearly after he remembered the past.
Even though he had rejected his offers several times, but the man was persistent enough to tell him his wishes. He continued begging for his help even though the real Uncle Qiu knew that he was being selfish. However, the latter continued to convince himself that they were helping each other --- he wasn't using Rong Qiu for the benefits of his own family.
