Happy shopping

Chen Mi looked at Yu Dong when he saw the latter nod her head, he sighed and then replied to the young mer, "It's two taels half a catty, if you want a catty then you will have to pay four taels." 

" Are you trying to rob us? How can tomatoes be so expensive?" Song Zhi recoiled as he looked at the big tomatoes which were sitting in a delicate wicker basket and were stacked nicely making them look alluring. If it was two taels a catty, he would have thought of buying them buy four taels for a catty, it was too much!
