边境天堂 A borderline paradise

板约-德天瀑布，中国与越南边境

欢迎来到河流与边界线交汇的绝美之地：板约-德天瀑布。今日图片展示的正是这幅美景。该瀑布位于中国广西壮族自治区大新县与越南高平省重庆县之间的喀斯特地貌山丘区，沿着归春河流下。瀑布高达95英尺，宽980英尺，是越南最宽的瀑布，距离河内169英里。多年来，板约瀑布的顶端因侵蚀而缓慢向上游延伸。一年中的大部分时间里，它们以两个独立的瀑布流淌，但到了夏季，当雨水使河水上涨时，它们会汇合成一个巨大的瀑布。

尽管道路得以改善，公共交通更加便利，无人机视频也展示了瀑布的壮丽美景，但板约瀑布依然保留着原始与静谧的一面。大规模旅游尚未波及这里，因此在大多数工作日，您只会遇到寥寥无几的游客、当地居民，以及瀑布奔涌的声音。

Bản Giốc–Detian Falls, Vietnam

Welcome to a spot where rivers meet international borders in the most stunning way: the Bản Giốc – Detian Falls, featured in today's image. Tucked between the karst hills of China's Daxin County and Trùng Khánh district in Vietnam, these falls tumble along the Quây Sơn River about 170 miles north of Hanoi. For most of the year, they flow as two distinct cascades, but come summer, when the rains swell the river, they merge into one big fall. At over 95 feet tall and 980 feet wide, Bản Giốc holds the distinction of being the widest waterfall in Vietnam.

Even with better roads, easier public transport, and drone videos showing off the jaw-dropping beauty of the falls, Bản Giốc remains refreshingly off the beaten path. Mass tourism hasn't caught up yet, and on most weekdays, you'll find only a handful of visitors—just you, the locals, and the sound of cascading water.

尽享欢乐时光 Ring in the fun

J.R.R.托尔金生日快乐！

“冒险是否会有尽头？我想不会吧，因为总有人要继续讲述这个故事。” 今天是托尔金日，全球的读者们共同纪念这位创造了中土世界史诗冒险故事的大师：托尔金。托尔金可能是故事的开创者，但他的读者才是故事的传承者，一代又一代的读者沉浸在《霍比特人》、《指环王》等作品中。托尔金的读者们每年都会组织传统的祝酒活动庆祝托尔金的生日，在当地时间的晚上9点站起来并举起酒杯，说一声“敬教授”，然后喝一口即可。

而今日图片中展示的正是可能启发了这位文学传奇的地方。位于英国牛津大学的拉德克利夫图书馆。这座圆形穹顶建筑最初是一座科学图书馆，现在是作为博德利图书馆的阅览室使用。据说，这座18世纪的建筑是托尔金小说中努曼诺尔上祭祀魔苟斯神庙的灵感来源。虽然托尔金并未在此学习，而是埃克塞特学院的学生，但他在担任牛津大学英语语言文学教授期间，曾无数次路过这座建筑，其非凡的外观至今吸引着游客和托尔金读者们的目光。

Happy Birthday, J.R.R. Tolkien!

'Don't adventures ever have an end? I suppose not. Someone else always has to carry on the story.' Today, on Tolkien Day, fans around the world honor the master storyteller who crafted the epic adventures of Middle-earth: J.R.R. Tolkien. While Tolkien may have started the tale, it's his readers who carry it forward, generation after generation, diving into the pages of 'The Hobbit,' 'The Lord of the Rings,' and beyond. Tolkienists are encouraged to celebrate the author's birthday with a toast at 9 PM local time—to participate, all you must do is stand and raise a glass of your choice, say 'The Professor,' and take a sip.

For today's featured image, it is only fitting to visit a place that might have inspired the literary legend: the Radcliffe Camera, or Rad Cam, at the University of Oxford in England. Originally a science library, the domed, circular building now serves as a reading room for the Bodleian Library. This 18th-century building is said to be an inspiration for Sauron's temple to Morgoth on Númenor in Tolkien's fiction. Though Tolkien himself didn't study there—he was a student at Exeter College—he would have passed by the Rad Cam countless times during his years as a professor of English Language and Literature at Oxford. This building, with its extraordinary exterior, continues to captivate visitors and Tolkien enthusiasts alike.

里约的午夜 Midnight in Rio

巴西里约热内卢的新年前夜

除夕，也被称为元旦，世界各地都会举行狂欢、烟花表演，以及一些宗教和文化仪式。许多国家用象征繁荣、长寿和来年好运的食物庆祝，许多人在午夜时分唱起苏格兰民歌《友谊地久天长》，纪念老朋友和过去的经历。在一个可以追溯到古希腊的传统中，新年通常被拟人化为一个婴儿，与一个代表即将结束的一年的老人配对。

聚会是迎接新年的常见方式，巴西里约热内卢举办了一场难忘的聚会。里约以许多事情而闻名，包括丰富多彩、热闹非凡的庆祝活动、美丽的海滩，以及今天在科帕卡巴纳海滩举行的免费除夕派对。当地人称之为Réveillon，这是世界上最大的除夕晚会，有数百万狂欢者。

New Year's Eve in Rio de Janeiro, Brazil

New Year's Eve, also known as Old Year's Day, is celebrated around the world with revelry, fireworks, and for some, religious and cultural observances. Many countries celebrate with foods symbolic of prosperity, long life, and good fortune for the coming year, and many people sing the Scottish folk song 'Auld Lang Syne' at the stroke of midnight in remembrance of old friends and past experiences. In a tradition that dates back to the ancient Greeks, the new year is often personified as a baby that is paired with an old man who represents the year that is ending.

Get-togethers are a common way to ring in the new year, and Rio de Janeiro, Brazil, throws a memorable one. Rio is known for many things, including colorful, exuberant celebrations, glorious beaches, and the free New Year's Eve party at Copacabana Beach, seen in today's image. Known as Réveillon to locals, this New Year's Eve soiree is the largest in the world, with millions of revelers.
