If you open the entry for the Battle of Chosin Reservoir on Wikipedia, you will see that the battle ended around December 13, 1950, with other claims being from December 10 to 12. However, the entry on Baidu Baike states that it was December 24.
There is a difference of 11 days, so is there a difference in perception? For example, one side thought there was fighting, while the other side had no impression. Baidu Baike explains it this way: “On the 12th, … the two divisions of the US military continued to retreat south … Along the way, although the remaining troops of the 20th Army continued to pursue, the main force of the 26th Army was never able to catch up and join the battle. In the impression of the US soldiers, they did not encounter any strong resistance in the later stages of the battle.”
Then December 24 was the time when the United Nations forces had completely withdrawn from Hungnam Port, which is probably how it is considered the end time. It’s like a website that is about to be shut down on December 24, but the website cannot be accessed around the 13th due to some media reasons. Whether the site is shut down on the 13th or the 24th is just a difference in perspective.
This kind of difference in perspective tends to make the more easily perceived side the mainstream view. Because the simplified Chinese version used to downplay the battle, the main view is not in simplified Chinese. Even the 2019 Baidu Baike wrote December 13.
After exploring the perspectives of Wikipedia (international researchers) and Baidu Baike (simplified Chinese official), there is still one perspective left, which is when did the remaining troops of the 20th Army, who were trying to block the United Nations forces at the time, think the battle ended?
If you don’t know anything and only see that the end time is December 24, and then don’t let others celebrate Christmas, such as by publishing an article like “China has no Christmas! December 24 is the day of victory in the Battle of Chosin Lake“, that is purely KY (cannot read the air), and even disrespectful to the soldiers.
