Sidai
From Wikipedia, the free encyclopedia
Sidai or Shidi (師弟) means junior fellow students in a Chinese martial art school. Si means teacher. Dai means younger brother. The seniority is not based on the student's age or level of skill, but on the chronological order of following a particular sifu. The master's first student is always the most senior sihing. The less senior students are called shidai among their peers.
