World's Deepest Lake, Once Part of Our Country's Territory, Now Requiring a Passport to Visit
When it comes to the world's deepest lake, what lake will you think of? It is Lake Baikal, which is currently the oldest lake in the world. It was once part of our Chinese territory during the Qing Dynasty, ceded to the Russian Tsar after the Treaty of Nerchinsk. Today's Lake Baikal has different scenery in all four seasons, but now you need a passport to visit. Let's take a look at how beautiful Lake Baikal is.


Lake Baikal is located in the south of Siberia, Russia, with a lake area of 31,500 square kilometers, the deepest point reaches 1,637 meters, and the average depth is 730 meters. So it is the world's deepest lake, the oldest lake, and the largest freshwater lake in Eurasia.

In ancient China, Lake Baikal was called Beihai (North Sea). It was once the exile place for Suwu during the Han Dynasty. Suwu was dispatched by the Han Dynasty to visit the (Huns) and was detained for a long time. After Suwu's sheep were kept by the Huns, they were able to produce lambs, so he was brought back. It is impossible for him to bring back those lambs. As a result, Suwu was exiled in Lake Baikal for 19 years.


Lake Baikal has different beauty in all four seasons; in spring, wildflowers are everywhere; in summer, the cool breeze blows; in autumn, the whole mountain is golden; and in winter, the lake water freezes completely, forming a snow and ice wonderland, like entering a beautiful fairytale world.

Because of Lake Baikal's beautiful scenery, many Chinese people come here to buy houses and land. The land here is private property, and you have permanent residence rights after buying it. It's no wonder so many people want to buy houses here, even the locals are starting to protest against Chinese people buying houses in Lake Baikal. Lake Baikal has a total of 22 islands, but only Okhotsk Island has residents, and it is also the largest island in Lake Baikal. Half of the island is a primitive forest, half is grassland, and a small part is desert, which is relatively suitable for living.

This is Lake Baikal in winter, with a freezing period of about five months. The average temperature of Lake Baikal in winter is as low as -38 degrees Celsius, so it starts to freeze in January and thaws after May, with a thickness of 70-115 centimeters, which is very cold.
