Ngai (嗌) means shout, while jong (莊) refers to the executive committee of a college, department or society under the university's students' union.
When proposed cabinets ngai jong, all members stand together and shout slogans, their full address, polling dates or sing songs to promote themselves.
Since ngai jong is a special cultural phenomenon of universities in Hong Kong, proposed cabinets will automatically do this as it is a part of the whole election.
Through shouting slogans and standing together publicly, the cabinet will have the chance to promote themselves and catch the attention of the people who walk by.
To the members of proposed cabinets, "Ngai Jong" is unforgettable, since it is a tiring but meaningful thing to do during the promotion period.
It requires creativity in designing the slogans and it brings physical challenges as cabinets need to stay overnight outdoors for weeks at the university entrance in order to get a good position that is eye catching.
Tourists are attracted by this activity, and people who visit the universities can experience and feel the spirit of competing cabinets.
"Ngai Jong" also arouses their sense of democracy as they have voting rights in the polling day to support the cabinet they trust.
