78 of our students and their parents participated in the flag selling day for Operation Dawn in the bright sunlight and warm breeze on 16 June, 2018. It was the first time our students using the portable Octopus readers to sell flags. It might seem convenient for making donation in the first place. However, it was quite a challenge as the amount of donation is restricted to $10 only. With great efforts of our students, we successfully helped in raising operation fund for the charity.
