Wai Kru

ceremonies are preferable held on Thursday, which is believed to be
the teachers´s day. On that day, pupils present certain offerings, usually flowers,
money, cloth, etc., to the person who has accepted them as his students. The pupils
make a vow that they will study seriously and patiently, respect him and behave
fairly to their fellow students and will use the knowledge gained properly.
Wai Kru is called Kheun Kru (the initial ceremony of paying respect to the
teacher).
