The school is organising an exchange student program, and is requesting all students who take design to go to Shanghai, to study at a local design school with local Shanghai students from september till december, and will come back to Hong Kong near Christmas.

At the time being, because of 2 fashion shows needed to be organised, a lot of things are needed to be prepared, including stage designing. Also there are 2 pieces of summer assignments needed to be done, there is not much time at the time being.
