... that between 1963 and 1979, the price of land in the Gangnam region(pictured) of Seoul increased nearly 1000 times? "The price of land soared: for example, in Gangbuk (the old urban center) the price of land increased by nearly 25 times, and in newly developed Gangnam it increased by nearly 1000 times." https://www.sciencedirect.com/science/article/pii/S0264275120314219 The source also shows the years in a table.
ALT1: ... that the rapid development of the Gangnam region(pictured) of Seoul was spurred by the 1968 North Korean assassination attempt on military dictator Park Chung-hee? "Concern over an invasion by North Korea was another motivation for Gangnam's development. Back in the 1960s, Korea was concerned about a possible reinvasion by North Korea. Gangbuk was more vulnerable, being only around 40 kilometers (25 miles) away from the demarcation line between South and North Korea that was created in 1953. The Blue House raid, launched by North Korean commandos to assassinate President Park Chung Hee in 1968, awoke the authorities to the need to disperse the population and public agencies further away from the demarcation line." https://koreajoongangdaily.joins.com/2023/02/11/why/korea-gangnam-development/20230211070009412.html and further elaborated in page 68 of https://www.jstor.org/stable/10.7591/j.ctv1xp9pw7.9 "In the event of an invasion by North Korea, which had always been a keen concern of the military government in South Korea, having three million people concentrated on the north side of the Han River would be a liability. This concern was heightened by a North Korean commando attack on the presidential palace in an attempted assassination of President Park Chung Hee in 1968."
for some reason the DYK tool bugged out while writing this and deleted my first two DYKs, I've re-added them now Freedom4U (talk) 04:56, 27 February 2023 (UTC)
Overall: @Freedom4U: Good article. Though, should "The music video was filmed in the Gangnam District and featured the ASEM Tower and the Trade Tower. The 2015 action film Gangnam Blues followed the real estate development of the Gangnam area." be cited? other than that everything seems good. AGF on Korean sources.

@Onegreatjoke: Huh I actually rephrased the first part from the Gangnam District article, but I didn't do it correctly because their source There's no Gangnam in Gangnam Style didn't actually say that... I've gone ahead and rephrased the sentence to better match the source. I've also added a source for the Gangnam Blues sentence now. Freedom4U (talk) 00:02, 1 March 2023 (UTC)
