Lau was in the first class to study in Taiwan's youth vocational training course. Courses are offered in universities, colleges, and vocational schools and aim to teach practical skills and production technology in industry, agriculture, and business to young overseas Chinese. Initially, 200-300 students were accepted into the programs per year, but that number has increased to 500-600 in recent years.
