YOSEMITE NATIONAL PARK, Calif. (AP) — A century-old building originally used as a laundry by Chinese workers at Yosemite’s iconic Wawona Hotel has been restored and turned into a visitor’s attraction, recognizing Chinese Americans’ contributions to the early history of the national park.

Officials unveiled a new sign Friday marking the Chinese Laundry Building in Yosemite Valley, the Fresno Bee reports. New exhibits inside tell the story of Chinese workers who helped build Tioga Road and Wawona Road, critical infrastructure that made tourism to the park possible.

The building — later used as a storage facility — is part of a cluster of structures that will make up the new Yosemite History Center, which will tell the histories of immigrants who made the park what it is today, said Park Ranger Adam Ramsey.

“Chinese people have been a big part of communities throughout the Sierra Nevada for a really long time, and it’s about time that we started sharing that history here in Yosemite,” Ramsey said.

According to research conducted by Park Ranger Yenyen Chan, in 1883 Chinese workers helped build the 56-mile (90-kilometer) Tioga Road in just 130 days. The stunning route across the Sierra Nevada reaches 10,000 feet (3,000 meters) in elevation and serves as one of the park’s main roads.

Chinese workers were also employed in Yosemite as cooks, laundry workers and gardeners.

Many first came to California during the Gold Rush, bringing with them skills learned in China about construction, engineering, agriculture, medicine and textiles that made a significant impact in America’s early success, Chan said.

She said Yosemite’s Chinese history and their contributions were erased from memory because of the 1882 Chinese Exclusion Act passed by Congress to prevent any more Chinese from entering this country in search of work. The law blocked Chinese immigration for 60 years in this country.

Members of the Chinese Historical Society of Southern California, who supported the building’s renovation, said they were gratified to see Yosemite include the Chinese in the park’s origin story.

“Something like this really resonates with a lot of people in my generation,” said Eugene Moy, a past president of the society. “We’ve been here since the 1870s, so to be able to see this has deep meaning, because a lot of us, oftentimes, are relegated to the margins. We aren’t always perceived as being full-fledged Americans when the reality is that people have been here for three, four, five generations, for 150 years.”

DUBAI, United Arab Emirates (AP) — After eight years of planning and billions of dollars in spending, the Middle East’s first world’s fair opened Friday in Dubai, with hopes that the months-long extravaganza will draw both visitors and global attention to this desert-turned-dreamscape.

The coronavirus pandemic pushed Expo 2020 back a year and may affect how many people flock to the United Arab Emirates. But the six-month-long exhibition still offers Dubai a momentous opportunity to showcase its unique East-meets-West appeal as a place where all are welcome for business.

Not long ago, the site of the 1,080 acre (438 hectare) Expo was barren desert. Now, it’s a futuristic landscape buzzing with robots that bark automated orders at bare-faced visitors to mask up, a new metro station, multi-million dollar pavilions and so-called districts with names like “sustainability” and “opportunity” — all built, like much of the Gulf, by low-paid migrant workers.

More than 190 nations are using their pavilions to spotlight their greatest tourist attractions, discoveries and ambitions. The American pavilion, paid for by the UAE after the U.S. could not raise the funds in time, boasts a replica of the Space X Falcon 9 rocket and takes visitors on a conveyor belt past multimedia infomercials for American inventions. It also displays a Quran that belonged to the nation’s third president, Thomas Jefferson, as an example of how religious freedom ”is woven into the very fabric of American society.”

China’s vast, lantern-shaped pavilion focuses on the nation’s space ambitions and future inventions, featuring a Transformer-like car that SAIC Motor hopes will function one day also as a submarine and helicopter.

Draped over Italy’s pavilion is 70 kilometers (40 miles) of rope made from 2 million plastic bottles. The main attraction, though, is a marble 3-D replica of Michelangelo’s biblical hero, David. The 5.2 meters (17 feet) high nude giant is not easily accessible — visitors must must enter separate floors of a building to view it at eye-level or peer up from its feet. Public nudity is outlawed in the UAE, where traditional Muslim norms largely prevail.

The UAE’s falcon-shaped pavilion, by far the site’s largest, takes visitors on a two-hour-long immersive experience through dunes of real orange sand and footage from the country’s 50-year history.

Other attractions include an African food hall, a massive mirror-like fountain with silver cascades of water flowing back and forth, a recently excavated royal Egyptian mummy, concerts and performances from around the world, and the option to dine on a $500 three-course meal with glow-in-the-dark cuisine.

As night fell and the call to prayer echoed musically through the grounds, pavilions came to life with lights, lasers and kaleidoscopic shows.

Isabel Fu, 50, said she flew in for Expo all the way from Beijing to see “the kind of changes that we’ll see in the future, the technology that makes us look forward to the next era.” Upon her return to China, she faces 21 days of quarantine.

Since first making a splash in London in 1851, world fairs have long served as an opportunity for nations to meet, exchange ideas, showcase inventions, promote culture and build business ties.

For more than a century, global exhibitions have captured the imagination and showcased some of humanity’s most important innovations. The first world’s fair held in the United States in 1876 debuted Alexander Graham Bell’s telephone, the typewriter, a mechanical calculator and Heinz Ketchup. One of its main buildings, Memorial Hall, is now a museum.

Other fairs introduced inventions like the sewing machine, the elevator, carbonated soda, the Ferris wheel and, in 1939 in New York, the television.

This year’s Expo is unfolding as the virus continues to course across the world, with untold numbers still working and studying remotely — and connecting to the world virtually. It’s unclear how many visitors Dubai can attract, and how much the Expo will stimulate its tourism-driven economy — especially in the blistering early autumn heat, which on Friday caused tempers to flare, some visitors to faint and most people to sweat through their shirts.

“We’re dying! Humans can’t tolerate this weather,” exclaimed 35-year-old Warda Abadi from Saudi Arabia as she shepherded her limping mother into the shade.

To enter the Expo site, visitors must show a negative PCR test or proof of COVID-19 vaccination.

Dubai’s ruler and the force behind the emirate’s transformation, Sheikh Mohammed bin Rashid Al Maktoum, described Expo 2020 as a chance to showcase the best of human excellence.

“It offers a platform to forge a united worldwide effort to build a more sustainable and prosperous future for all of mankind,” he told guests at the Expo’s opening ceremony.

Sheikh Mohamed bin Zayed Al Nahyan, crown prince and de-facto ruler of the UAE’s seat of power, Abu Dhabi, emphasized “the ethos of this land” as a meeting point for cultures and tolerance.

Whether Iran or Israel, every nation is welcome at Dubai’s Expo. The space marked for Afghanistan’s pavilion, however, appeared vacant weeks after the Taliban takeover of Kabul.

“It makes me very proud to see so many different kinds of cultures, countries and traditions coming to my country for the first time,” said Isa Nuaimi, a 25-year-old government pilot from the Emirati city of Al Ain.

Human Rights Watch, however, said that the UAE’s efforts to promote itself as an “open and tolerant country” remain at odds with its human rights abuses, including the suppression of peaceful criticism, jailing of activists and pervasive government surveillance.

“The UAE has embarked on a decades-long effort to whitewash its reputation on the international stage,” the rights group said.

The Expo site will attempt to dazzle visitors with a centerpiece dome, marketed as the world’s largest 360-degree projection screen.

Some world’s fair structures remain iconic markers of the human journey and our industrial evolution. None more so than the Eiffel Tower, which was constructed in Paris, not only to be the tallest structure in the world at the time, but to serve as the entrance to the 1889 world’s fair. The Space Needle in Seattle, Washington, built for the 1962 world’s fair, also continues to enjoy global prominence.

While most fairs were held in Europe and the United States, none have been hosted in the Middle East until now.
