Inevitably, Mr Tam of the DAB and Mr Leung of the Neighbourhood and Workers Service Centre in New Territories West were bound to be confused.
A Leung campaigner was talking to a woman in Kwai Hing who had promised to vote for Mr Leung.
'I'll vote for No 7, no problem,' she said.
Shocked, the Leung team member said: 'Our candidate number is three. Tam Yiu-chung is No 7.' A supporter of Liberal Party Kowloon West candidate Ringo Chiang Sai-cheong seemed to be overcome by nostalgia yesterday.
After hours campaigning for Mr Chiang in Oi Man Estate, Ho Man Tin, the woman jumped up to greet her idol.
