The Scum Is Ashamed 

CLUNK! CLANG! A gold coin fell on the tin can and made the tin can rattle in the ground before it stopped. The beggar who is tapping the top of the tin can using his walking stick stopped and placed his walking stick to the side. 

"Excuse me." Cheng Sheng called as he squatted before the beggar wearing a conical hat. "Can I ask a few questions from you?" he said as he looked at the beggar whose conical hat is too low, hiding his face. 

The beggar didn't answer, but Cheng Sheng, Fei Yin and Wu Yuan saw the beggar held his walking stick and tapped the top of the tin can twice. Cheng Sheng, Fei Yin and Wu Yuan looked at each other before they decided that the beggar must meant 'you may' by that gesture. 

Cheng Sheng turned to the beggar and spoke. "Do you know where is the Shashan Pass?" he asked. 

The beggar tapped the top of the tin can twice again. Cheng Sheng, Fei Yin and Wu Yuan decided that the beggar must meant 'I do' by his gesture.
