When I was a Custom Officer in Hong Kong, I have trained as a dog handler and a dog instructor in Surrey Police Training School in 2012 and 2018 respectively. I worked with my dangerous drug detector dog Buddy in Hong Kong border between 2012 and 2018. Between 2018 and 2022, I was a leader to lead a dog detector team. Then, Buddy emigrated to UK with my family in July this year.
