Lanzhou, Gansu, China: The Silk Road Town with the Yellow River Passing through the City

Lanzhou, the capital of Gansu Province, is located in the northwest of China in the Yellow River Valley Basin, and is the only provincial capital where the Yellow River passes through the city. As an important transportation hub and commercial port on the ancient Silk Road, Lanzhou has a history of more than 2,000 years and is known as the "Golden City". With four distinct seasons, dryness, little rain, and a large temperature difference between day and night, Lanzhou has a temperate continental climate.

Lanzhou is famous for "a bowl of noodles, a book and a river": the beef ramen is famous all over the country, the circulation of "Reader" magazine is the first in Asia, and the Huanghe Wind Wind Line shows the unique cityscape. Major attractions include the Yellow River Iron Bridge, the White Pagoda Mountain Park, the Waterwheel Expo Park and the Gansu Provincial Museum (which houses national treasures such as the Horse Treading Swallow). Nowadays, Lanzhou has become a comprehensive transportation hub and a modern industrial center in Northwest China, with well-developed industries such as petrochemicals, equipment manufacturing, biomedicine, etc., and the Chinese-European liner trains converge here, making it a key node city of "One Belt, One Road".

Ruby, Louisiana, USA: The epitome of a quiet Southern town

Ruby is a small incorporated town in Tangipahoa Parish, Louisiana, United States, located about 60 miles northeast of the state capital of Baton Rouge and adjacent to the Mississippi border, and characterized by a quiet rural atmosphere and a deep community culture. Sparsely populated, with fewer than 500 people according to the most recent census, the town dates back to the late 1800s and, with its early rise to an agricultural economy (e.g., cotton and soybean farming), still retains the rustic look of a traditional Southern town. The town's landmarks include a century-old community church and several Victorian-style homes, and the annual fall "Ruby Family Day," which blends elements of local Cajun and Creole culture, has become a shared memory for the surrounding residents. Despite its small size, Ruby epitomizes the serenity of the American countryside with its simple folk and distinctive Louisiana southern flavor.
