If you have a foreign friend who does not understand any Thai culture. How would you explain your friend to know how important Wai Kru Ceremony?

In my opinion, the Wai kru ceremony and teacher’s day are equally important because it is a day to remember the teacher’s pity or a teacher-focused day. But what is different is that when the ceremony is held by the day of the Wai kru ceremony, the teachers have Thai respect.
