    Leaving Hanoi on a fiercely hot summer day,after an hour by air,Luang Prabang gradually appears below our airplane wings.From a few hundred meters above,my first impression of this UNESCO-listed heritage（遗产）is an area of green land and mountains,surrounded by snaking rivers.

    Encircled by mountains,the former royal capital of Luang Prabang is more than just the country's picture-perfect showpiece.

    Travelers will be attracted to Luang Prabang by the city's timeless peacefulness with its shiny Buddhist temples, French colonial architecture and friendly people.

    Tourists visiting Luang Prabang shouldn't miss the chance to see one of the most sacred（神圣的）Lao traditions, tak bat,or the Buddhist almsgiving ritual（仪式）,which dates back to the 14th century.

    As the sun rises in Luang Prabang,hundreds of Buddhist monks depart from their temples to gather their daily offerings,which most commonly are rice,fresh fruit and traditional sweet snacks.The daily alms gathering begins on the main street before spreading to all the side streets.

    Our group of six got out of our comfy beds at 5 am to join other local residents and tourists to offer alms to the monks.We kneeled by the roadside in front of the 3 Nagas Hotel on the main street with big baskets of steamed sticky rice,waiting quietly until monks of all ages passed by to accept our gifts.

    The daily ritual gives you a wonderful opportunity to experience an ancient Lao tradition.However,there are some strict rules if you wish to join the event.

    Firstly,shoulders,chests and legs must be covered in modest clothing as a mark of respect.You should also remain a suitable distance from the monks.Photographs may be taken,but from a distance and never use a camera flash.The ritual has to be performed in silence.Talking to or touching the monks at any time,even when making an offering,is not allowed.

    Another must-do morning activity is to visit the local market,where you can see the generosity that Mother Nature offers this dreamy land.While walking through the morning market,located within a long and narrow hamlet,I was excited to see all kinds of products from the nearby river and jungle: some ill-fated squirrels lying next to fresh bamboo shoots,different kinds of wild mushrooms and vegetables displayed on banana leaves and giant river catfish in baskets.

    Although Luang Prabang is small,there are many things to see here.Active travelers can get up close and personal with Laos' gentle giants at the elephant conservation camp or take in some scenes of riverside life with a cruise or kayak excursion on the rivers.Two waterfalls that are perfect for picnicking in the foothills nearby,and classes are available in traditional crafts.

    The legal age for drinking alcohol（酒精饮料） in the US is twenty-one. Underage drinking is not only a crime but also a common part of college social life. This week in our Foreign Student Series, we look at alcohol policies at American colleges and universities.

    The United States has more than 17 million students in higher education. Each year, 1,700 of them aged 18 to 24 die from alcohol-related road crashes and other injuries. 600,000 more are injured because of alcohol. And almost 700,000 are attacked by another student who has been drinking.

    Now, many schools have begun to strengthen（加强）their rules and college officials are trying to prevent too much drinking. Some researchers have found that students who think heavy drinking is normal often think that other students really drink much.

    At the University of Oklahoma, new policies came into effect after a nineteen-year-old student died from drinking too much at a party. Now alcohol is banned（禁止） from all university housing. Student organizations can serve alcohol at events but only on Friday and Saturday nights. And they must provide for transportation to and from off-campus parties. Other new requirements include an alcohol educational program that first-year students take online.

    The policies govern behavior on campus and off. With the first violation（违规）, students pay

75 dollars and their parents are told. They must also take an alcohol education class. They have to pay double if the behavior happens again. Those who violate a third time will have to be driven home for at least one term. The president of Oklahoma says the aim is not just to punish but to change the behavior and the culture at the university.

    Alan Naiman was known for being very careful about how he spent his money. But even those closest to him had no knowledge of the fortune he quietly gathered and the last act he had planned.

    Naiman died of cancer at age 63 last January. The man from the American state of Washington gave most of his money to groups that help the poor, sick, disabled and abandoned children.

    He gave them $11 million. The large amount of his fortune shocked the groups that received his gifts and even his best friends. That is because Naiman had been known to repair his own shoes with duct tape. He had sought deals to buy food from grocery stores at closing time and taken friends out to lunch at low cost restaurants.

    Naiman died unmarried and childless. He loved children but also was intensely private. He saved, invested and worked extra jobs to gather money. He rarely spent the money on himself after seeing how unfair life could be for children who suffer most.

    Naiman was a former banker who worked for the past 20 years at the state Department of Social and Health Services. He earned $67,234 a year and also took on side jobs. Sometimes, he worked as many as three at a time. He saved and invested enough to make several millions of dollars. He also received millions more from his parents after they died.

    He left $2.5 million to the Pediatric Interim Care Center in Washington. The center is a private organization that cares for babies born to mothers who abused drugs and children with drug dependency. The center used the money to pay off its mortgage (按揭) and buy a new vehicle to transport the children.

    Naiman gave $900, 000 to the Treehouse, where children without parents can choose toys and necessities for free. Treehouse is using Naiman's money to expand its college and career support services Statewide.

The Aviation Industry Corporation of China (AVIC), China's leading aircraft maker, created the country's first fully solar-powered drone (无人机). The large drone, Qimingxing 50, took off at 5:50 pm on September 3rd, 2022, from an airport in Yulin of Shaanxi Province and stayed in the air for 26 minutes before landing on the same runway. AVIC said that all systems of the unmanned plane functioned well on its first flight.

Powered by six electric motors with solar batteries, the drone is designed to conduct long-time operations in near space. Near space is that part of Earth's atmosphere at altitudes of 20 to 100 kilometers. It is above the top altitudes of commercial airliners but below orbiting satellites.

Qimingxing 50, also called "quasi-satellite", features high operational efficiency and eco-friendliness and will be tasked with high-altitude reconnaissance (侦察), forestry fire monitoring, atmospheric environmental inspection, aerial mapping, communication signal relay and other operations.

"Thanks to its capability to conduct very long endurance flights in near space, the drone can essentially become a substitute for satellites," a Chinese aerospace expert said. Satellite services are not always available due to the limited number of satellites and relatively fixed schedules of overhead passes. In time-sensitive missions, near-space drones can offset these disadvantages, the expert said, noting that satellite services could also be damaged in wartime, so near-space drones could replace them in this occasion.

The successful first flight of the Qimingxing-50 lays a solid foundation for the development of key technologies in the country's new energy field, the composite (复合的) material field, which will enhance China's ability to perform tasks in near space and over far oceans. AVIC will seize the opportunity to increase investment and speed up the development of large solar-powered unmanned aircraft.
