Su Wan earned two copper coins by posing as a beggar, and with them opened the door to her business career. She only wanted to run an honest business, but soon learned that getting by without powerful backing was impossible, so she had to cling to someone influential. Then one careless slip of the tongue dug her a money-guzzling hole. What was she supposed to do? Make the best of it, of course! Su Wan spent her whole life filling in the holes she had dug, and became the female teacher to students from humble families across the country.
