My story begins at the end of the movie after Marlin and Dory have finally found Nemo.

After experiencing much obstacles and difficulties, Marlin and Dory finally found Nemo and three of them lived together. Dory's memory had become normal and she brought much happiness to the father and the son. Their happy life continued until one day…

One day in the morning, Dory woke up in the coral as usual because after living with Marlin and Nemo, she had already adapted to the life in the coral and had made good friends with corals. When she came out of the coral to enjoy the fresh water for a new day, she noticed something strange in a place not far from her. Many stones were piled together. When Dory came closer to the stones, she found out it was actually a cave. Out of curiosity, she decided to go inside and to check out. Although it was early morning, the inside cave was still quite dark which made Dory a little bit frightened. To build up courage, she was singing while going deeper inside. On each side of the wall inside the cave, there were many fresco which seemed to be date back to the ancient China. In some pictures, people were writing something carefully in a small room, which seemed like they were taking the annual exam to get qualification to work for the emperor. In other pictures, prosperous scenery was shown that common folks were gathering in a market to see a Kongfu performance. When Dory were trying to figure out the meaning behinds these paintings, she arrived at a gold door. The door was made from steel and had a huge picture on it. Unlike the fresco on the wall, this picture actually looked like a traditional Chinese word with many letters. After finding out it was locked, Dory became confused and a little bit angry. "What on earth is inside in the door? I need to think about a way to go inside", said Dory. Fortunately, when she was swimming back and forth, she found out some Chinese words on the wall. But what strange was that there were some empty spaces close to those words and both the words and the spaces were embedded in the wall. It seemed that these Chinese words were related to the locked door close to them. So Dory was aware that to open the door, she needed to figure out what these Chinese words meant and how the empty spaces were used first.
