Cheng explains what he sees in the story now: "The treasure box contained Urashi-ma's time, which the Dragon King wished to return to him. It was out of good intentions that the Dragon King told him never to open it, but fate has it that he does."
「寶盒裡裝的是浦島的歲月，龍王送他寶盒是要歸還他在龍宮的歲月；叫他不要打開是善意，他打開寶盒卻是宿命。」
