Drawing just one Mah-jong tile is the easiest and probably the most common method of reading. Without a storyline like when interpreting a layout, there are no tiles to compare and contrast. Simply interpret the tile as the answer to the question.
Alternatively, this method may be used repeatedly in succession to allow the tiles to tell a story.
The Dragon tile embodies good fortune. It tends to mean a massive and sudden gain not tied to any specific efforts made on your part. This tile suggests that a pleasant surprise may be right around the corner.
