The Feast of Immaculate Conception was held on December 6, 2019. The theme this year is "Do Your Best-Do Everything with all Your Heart". Celebration etiquettes were held in the School Hall and covered playground respectively.

In the School Hall, Father Peter Ng, the dean of Salesian House of Studies, held a mass for Catholic teachers and students, members of the Salesian Youth Sodalities and catechesis classes. He reminded students to imitate the virtues of the Virgin Mary in Annunciation: listen attentively to God's words; ask questions if you don't understand; have trust in God, so we can do our daily routine the best, and sanctify ourselves and others.

In the covered playground, Mr. To Chun Hing, a social worker, shared his thoughts with the non-Catholic teachers and students in the prayer meeting. He shared his growing up experience, from sudden blindness due to illness when he was in form 5, to his efforts to overcome visual impairment, and finally becoming a social worker serving youth at risk with his hard work. He is also a dancer, and he used his experience in dancing to testify, telling the participants how to do everything with all his heart.

After the etiquettes, students participated in different recreational activities. All activities ended before noon.
