Here is a little story/legend I heard of
When Lu Ban was young & a skillful carpenter, He wanted to be the best.
He was seeking an opportunity to be accepted as an apprentice by a master carpenter, which was very famous nation-wide at the time
(actually in a neighbor country, since China was divided as many countries then
)
After passing some rigid trials, the master gave him the final test. He asked " Once upon a time, there were two
great apprentices, both worked hard through their lives, the elder one marked his name in people's heart, the younger one earned himself a gold mountain, which example would you follow?"
Ban made his choice and became the apprentice of the master.
He later invented saw, carpentry ink line,carpenter's plane, kite, ladder, and many many other useful tools and benefit the whole world.
There are people who still celebrate his birthday nowadays.

Of course, this was over 2000 years ago, maybe totally nonsense nowadays.
