Ladies and gentlemen, welcome to the Oriental Pearl Tower, a symbol of Shanghai's modernity and a marvel of Chinese engineering.
Today, we stand before the tallest structure in Asia and the third tallest in the world. This architectural wonder, designed by the imaginative architect, Zhu Peixuan, was completed in 1994 and stands at an impressive height of 468 meters.
As we look around, you'll notice the unique design of the tower, with its eleven ball-shaped structures, ascending from the green grass to the sky, symbolizing a 'Pearl' amidst the 'Sea of People.' The two largest spheres, resembling red rubies, are the most striking feature, creating an enchanting scene that reflects the poetic phrase 'big and small pearls falling into jade plate.'
The tower's design is not just for show; it's a testament to China's advanced engineering capabilities. The tower is composed of three inclined cylinders, three vertical cylinders, and eleven spheres, forming a massive space frame structure. Inside, you'll find a variety of attractions, including observation decks, a rotating restaurant, and even an amusement center.
Let's now take the elevator to the upper sphere, where we can enjoy a panoramic view of Shanghai. At 267 meters, the rotating restaurant offers a dining experience like no other, where you can savor delicious cuisine while gazing at the city's skyline.
As we continue our ascent, we'll pass through the five smaller spheres, which house luxury hotels. At the very top, the Space Module, at 350 meters, provides an exclusive viewing experience for our international guests.
The tower is not just a landmark; it's a cultural hub. The Shanghai History Museum, located at the base of the tower, showcases the city's rich history and cultural heritage through its extensive collection of artifacts and historical records.
As we conclude our visit, I hope you've gained a deeper appreciation for this magnificent structure and the vibrant city of Shanghai. Thank you for joining me on this journey, and I wish you a wonderful day ahead.
