Living off his wife.

"More beautiful gems, tsk, tsk, little sister, if I didn't know better I would think that you owned a couple of mines at home."

Tai Ho Sun looked at the rubies in front of him and he smiled obscenely. The smile stretched from ear to ear, which resulted in Caishen frowning even more than he had done when they met him at the same hotel where they were supposed to meet madam Qian. 

"I do." Alix responded freely, in a child like voice infused with enthusiasm.

Caishen rolled his eyes and glared at her. 

"Talk properly." he whispered to her. 

Even though he was whispering, his voice was loud enough to be carried into Tai Ho Sun's ears.

Tai Ho Sun saw an opportunity to tease the cold brother-in-law who didn't spare a smile for him even out of courtesy and he decided to take advantage of it and tease him. 

"Ooh, little sis, does this mean I can retire and live off you from now on?"
