This document outlines a marketing campaign to promote handwritten letters for Teachers' Day in Vietnam. The campaign will target secondary and high school students through three stages: 1) Create a viral video showing a teacher's reaction to receiving a handwritten gift; 2) Host an online debate on Tiki.vn about handwriting vs. digital messages; 3) Conclude with a recap video emphasizing the value of handwritten notes to encourage the tradition. The campaign will utilize online channels like Facebook and offline channels like magazines to promote the debate and encourage handwritten gifts for Teachers' Day.
