Chongqing – Nightlife in the Chinese megacity | DW Documentary

Posted on September 30, 2024 by agogo22

If you want to experience China, you can’t avoid Chongqing. This megacity is growing at a blistering place. But beware, it is not a place for anyone with a fear of heights, or a sensitive stomach.

The population of Chongqing, in southwestern China, has exploded over the last 30 years: now, some 32 million people live here. Covering an area the size of Austria, Chongqing is one of the largest cities in the world in terms of physical size.

In China, the megacity has become a tourist magnet. It’s known for its unique spots for snapping photos, like the train that runs right through the eighth floor of a high-rise building. Social media influencers have contributed to popularizing the city, once known mainly as an arrival or departure point for cruise tourists.

The people of Chongqing have a reputation for being particularly warm-hearted. City guide Zhen Jili, for example, knows every corner of his city, and has witnessed first-hand how his “big village” became a megacity. He takes visitors through his remarkable metropolis, where GPS is useless, because you never know which floor your destination is on.

Professional “designated driver” Shen Xun takes the film’s viewers along on his journey through Chongqing’s raucous nightlife, where the party doesn‘t end until morning. Because there is a strict ban on drinking and driving in China, anyone who has had a drink can call Shen Xun. He then arrives on his little folding bike, which he stows in the trunk before chauffeuring his customers home in their car.

Livestreamers like Paipai can be seen on every street corner in Chongqing. She explains why livestreaming is a billion-dollar business in China, and takes viewers to one of the city’s tallest buildings, for a view from right in the middle of the skyline.

Watch and Learn How the Fotoplayer Added Sound to Silent Films | My Modern Met

Posted on September 30, 2024 by agogo22

By Regina Sienra on September 29, 2024

“The fotoplayer used a fascinating combination of piano, organ pipes, drums, and various sound effects designed to narrate the action of any silent film.”

Back in the day, silent films weren’t limited to accompanying music. Thanks to a very clever instrument known as the photoplayer or fotoplayer, pictures got diegetic sounds such as thunder, bird chirps, doorbells, and gunshots, as well as a whole orchestra-worth of musical instruments.

These instruments appeared in 1912, falling out of fashion with the arrival of “talkies” in the late 1920s. According to the Silent Cinema Society, less than 50 survive, and of those, only 12 are known to be in playing condition. One of those can be found in the home of Joe Rinaudo, a Silent Cinema Historian and Preservationist, whose devoted work has even caught the attention of the Academy of Motion Picture Arts and Sciences, which hands out the Oscars.

Rinaudo’s interest in films began in the 1950s, watching silent cartoons and comedies on black & white television. Moved by this interest, in 1976, he purchased a 1926 fotoplayer. The instrument belonged to a theater in Saskatchewan, Canada, but was built in Van Nuys, meaning that Rinaudo went through the endeavor of shipping it back to California before fully restoring it.

“The fotoplayer used a fascinating combination of piano, organ pipes, drums, and various sound effects designed to narrate the action of any silent film,” explains the Silent Cinema Society, “This resembles a player piano, but with two rolls for changing music for different scenes; an assortment of pull cords, levers, buttons and stops connected to a side cabinet containing organ pipes, percussion, brass, sound effects, and literally bells and whistles. The pianist usually lets the rolls play the music while he selects the instrument stops and creates the sound effects. He’s watching the film, of course, all at the same time.”[…]

The American origins of the Chinese takeout font

Posted on September 29, 2024 by agogo22

Chop suey fonts are a subcategory of so-called “ethnic” display fonts, and are a unique American invention with roots in the 170 year history of Chinese migrants in United States.
