On 22-Mar, we were pleased to be invited by Macau Deaf Association for organizing a workshop of tie dyeing, which is one of our the community service activities serving the environment this year, for their users. During the activity, we shared the concept and importance of environmental protection, and the methodology of tie dyeing to participants. All of them had enjoyed the activity and produced their own unique item. We are grateful to have this opportunity to arrange this meaningful workshop for the needy. Look forward to convey the environmental protection message to more interested parties.
