"My sister can be bad-tempered sometimes," Wang Yao said.
"She's fine to me," Du Mingyang replied.
"That's good," Wang Yao said.
Crackling! He took a piece of concrete from the wall.
"Hmm, the quality of this building is terrible!" He broke the piece of concrete into pieces.
"Really?" Du Mingyang picked a small piece of concrete form the floor and squeezed it hard.
"Ouch! Is there anything else?" Du Mingyang asked.
"No, let's go back," Wang Yao said.
They went back to Wang Yao's home. Du Mingyang had a feeling that his future brother-in-law wanted to tell him something.
They had an early dinner. Wang Ru and Du Mingyang left right after dinner.
"Ru, can I ask you something?" Du Mingyang asked when he was driving.
"What?" Wang Ru said.
"Does Yao have any other skills apart from treating all kinds of illnesses?" he asked.
"Oh, he practices Kung Fu," Wang Ru said.
