The Tiger Hill Pagoda is a dazzling gem of traditional Chinese art, and the Leaning Tower of Pisa in Italy is a wonder of the world's cultural heritage. Both of them are unique representatives of the Eastern and Western cultures. In 2019, in coincidence with the 49th anniversary of the establishment of diplomatic relations between China and Italy, in order to ignite different colored sparks between the Eastern and Western cultures, the Suzhou Tiger Hill Management Office is hosting the International Invitational Poster Exhibition: Two Leaning Towers as a joint contribution to creating an urban culture between China and Italy.
