Wah Yan International Reunion (“WYIR” and formerly known as IC or Wah Yan International Conference) is one of the important events for Wah Yan alumni across the globe to meet together. The first Wah Yan International Conference ran in 1988 with the theme, Wah Yan Family Around the World. After that, WYIR holds every two years and has the following four key objectives:
- To provide fellowship opportunities between local and overseas Wahyanites
- To allow Wah Yan alumni all over the World to better understand the wellbeing of each other
- To keep alumni informed about both Wah Yan Colleges in Hong Kong and Kowloon
- To explore possible improvements on our Global Link networking
The 16th WYIR will be held in Hong Kong from 29 November 2019 to 1 December 2019 and co-organised by the past student associations of both Wah Yan Hong Kong and Wah Yan Kowloon.
