On behalf of Princeton University, 1 would like to convey my warmest congratulations to the faculty, staff, and students of The Hong Kong Polytechnic University as you mark 75 years of career- and application-oriented learning. From its modest beginnings as a government trade school, your institution has grown to become a dynamic presence not only in Hong Kong but also in mainland China and beyond, and I wish you every success as you find new and ever more innovative ways “to learn and to apply, for the benefit of mankind. ”
