Grandmother Lee was returning to Hong Kong. She had spent summer with her son and his wife, who lived in Europe. In her luggage she had a large bottle, a bottle of the famous "holy water" from a certain city. Some people said the water had special powers and even made miracles happen. Grandmother Lee wanted some in case she was ill. Perhaps it could help her elderly friends too. Grandmother Lee's son didn't believe the water had any special powers, but he helped her buy some. A good son, he wanted to make his mother happy.
