Lies and deception

"What do I not know?" Master Bing could not help but question with a frown on his face. He really hated it when someone talked in circles with him instead of telling him what was the matter. 

The mer sighed and stated, "Master Bing, I really pity you. You and your wife refused to follow your in-laws, and now your sister-in-law is working with Madam Yu at a big slaughterhouse. I heard that even a single pork hock from that slaughterhouse is sold for more than three taels. Do you even know how much money your sister in law is earning now? She is earning thousands of taels!" 

Boom! 

Master Bing felt like he had been struck with lighting, he stumbled and almost dropped the vegetables that he was carrying in his hands. If not for the fact that the mer caught him, Master Bing would have fallen on the ground. 

Thousand of taels? How much money was that!?
