Based on the animation of "Joseph Needham Says Ancient Chinese Textile Technology", participants must answer three questions provided on Quizizz and share it to three of your friends and leave your email to us. The three participants who get full marks in online quiz will have the opportunity to receive one gift. If more than three participants get full marks, we will draw three participants with full marks in the form of lucky draw. Winners will be notified individually by email within 7 calendar days after 25/04/2020.

Please be reminded that each participant is eligible for playing the online quiz once. For any participants who play more than once, only the first result will be counted.
