To foster a stronger Mid-Autumn Festival atmosphere and strengthen students’ awareness of the culture of the Mid-Autumn Festival riddles, The Primary School held a guessing riddle on the eve of the Mid-Autumn Festival for students to dip into the culture. All students were welcomed to create the riddles while senior students were invited to serve as helpers to check the answers for the participants on the riddle day to allow more student interactions. The performance of student guessing ability was linked to the results of the inter-house achievement. The vibrant surrounding and fervid students engulfed the covered playground completely.
