"最后，在1972年，苏联的西伯利来切尔斯基地区见证了至少10万青年学生在寒风中死去的一幕。"
The man think the main flaw of the story is this sentence.First , what is "西伯利来切尔斯基',Then the number 100,000 is not real.

Then I try to prove the story is true.

This is a slip of pen about Siberian, it should be "西伯利亚" rather than "西伯利来", then "切尔斯基” is Chersky. Form this article/(English Version), I learn the Chersky is a zone which have a concentration camp of former Soviet Union .

then 100,000 young man have possible to dead in Chersky.

And now, I should find the fact about the killed human in Chersky about 1970s.

Gulag

System of Soviet labour camps and prisons that from the 1920s to the mid-1950s housed millions of political prisoners and criminals.

The term (an abbreviation of the Russian words for Chief Administration of Corrective Labour Camps) was largely unknown in the West until the 1973 publication of Aleksandr Solzhenitsyn's Gulag Archipelago. The Gulag consisted of hundreds of camps, under the control of the secret police, where prisoners felled timber, worked in the mines, or laboured on construction projects. At least 10% died each year from harsh working conditions, inadequate food, and summary executions. The Gulag reached its height in the years of collectivization of Soviet agriculture (1929–32), during Joseph Stalin's purges (1936–38), and immediately after World War II, shrinking only after Stalin's death in 1953. An estimated 15–30 million Russians died in the camps.

Gulag
Gulag (, ) was the government body responsible for administering prison camps across the former Soviet Union. The word is an acronym for Главное Управление Исправительно—Трудовых Лагерей и колоний, Glavnoye Upravleniye Ispravitelno-trudovykh Lagerey i kolonii, "The Chief Directorate [or Administration] of Corrective Labour Camps and Colonies" of the NKVD. Anne Applebaum, in her book Gulag: A History, explains:
The word "Gulag" has also come to signify not only the administration of the concentration camps but also the system of Soviet slave labor itself, in all its forms and varieties: labor camps, punishment camps, criminal and political camps, women's camps, children's camps, transit camps., Even more broadly, "Gulag" has come to mean the Soviet repressive system itself, the set of procedures that prisoners once called the "meat-grinder": the arrests, the interrogations, the transport in unheated cattle cars, the forced labor, the destruction of families, the years spent in exile, the early and unnecessary deaths.[1]
