On the occasion of the renewal of Vientiane in the early spring, we sincerely invite all the alumni of the fifth and tenth year of graduation to return to the alma mater to relive the campus life, recount the friendship between teachers and students, feel the development of the alma mater, and compose a beautiful chapter!
