Supreme Patriarch Sangwol Wongak made his pilgrimage to Gukcheongsa Temple, Tiantai Mountain and entrusted his students to do saying "If diplomatic relations between Korea and China will be established in the future, Make your pilgrimage to Gukcheongsa Temple, Tiantai Mountain, the basic sacred place of Tiantai Buddhism."
