Afanti's story

Once upon a time, there was a long-term worker who worked hard at Master Bai's house for a year but didn't get a single copper. So he asked Afanti to help him ask for wages from Master Bai. Mr. Bayi sneered with his pipe in his mouth and said: "I can give you the salary, but all my money is with my accountant. Starting from September 1st, I have to go out to collect accounts for three consecutive days before I have a day off. My accountant The husband has to collect the accounts for five consecutive days before he can take a day off. When we both have a rest at the same time, you can come and get it." Afanti thought about it and left with the long-term workers. On that day, Afanti really got his wages from the long-term workers of Mr. Bayi’s house.
