Please note that from July 2002, the usual schedule of members’ meeting is changed to the second Tuesday of each month.

The Society will gradually resume the monthly members’ meetings and other outdoor / indoor activities.  Since the government restrictions are not fully relaxed and the threat of future new virus variants is not eliminated, we will monitor the latest arrangements and inform members if the situation changes.

Please note that participants must abide by the rules set by the government and the activity venue, and are advised to use “Leave Home Safe” app, and download the COVID vaccination record for checking.
