When carpenters make tables, doors, windows and furniture, they will use a ruler one foot, four inches and one quarter long. Rulers not only have dimensions, but also words to ward off evil spirits and take good luck. People call it Lu Banchi, also called secretary.
It is said that Lu Ban and Wen Gong are both famous craftsmen, but Lu Ban is always superior, which makes Wen Gong very jealous.
Once, these two men were ordered to lead their people to build a palace. While people were not looking, Jin Wengong sawed the ruler that Lu Ban used to measure the length short and changed it from one and a half feet to one and a half inches. When Lu Ban's disciples used this ruler to cut wood, they found that the length was wrong. Time was short and materials were exhausted. Lu Ban used his quick wits to replace the insufficient length with a stone pier, and the result was more solid and beautiful.
The king was very satisfied. When people asked him how he had such a whimsical idea, Lu Ban smiled and replied, relying on the ruler given by Wen Gong! From then on, Wen Gong was convinced. This ruler has been handed down to this day.
