There are still a large number of people in Hong Kong who support the police but do not know how to express themselves or dare not speak out their opinions, Yeung said. "I came across an elderly lady on the street one day, who rushed to me, grabbed my hand, and told me with tears that I spoke out what she wanted to say."

Yeung urged more Hong Kong people to disassociate themselves with violence and voice their support for police officers.

"We need more people to stand out bravely and say no to violence," Yeung said. "Now is year 2020, I hope demonstrators can use modern, civilized means to express their opinions and requests instead of primitive ways."

"Only when unrest ends can we rebuild our home and bring back our peaceful lives. And then Hong Kong will recover very fast just like many other hardships we went through before," he said.

"I for 100 percent believe that."
