In Zhongliao, Nantou, there is the only cypress vine avenue in Taiwan. It is hidden deep in the countryside and forests. If the speed is too fast, it will accidentally flash past. It is a real secret place for viewing flowers. The tin leaf vine, also known as the wishing vine, was originally a native species of Mexico and Central America. Because the leaves are rough as sandpaper, they are often used for rubbing ivory chopsticks and tin utensils, but in Taiwan they are mostly used as ornamental plants.
