[Eng Sub] The secret of Korean bullet train car No. 5 (KTX seat selection tips)

When many people book a KTX general room on the Korail website or Korail Talk app,
They pay attention to window seats or aisle seats, but they don't seem to pay much attention to car selection.
KTX is also a general room, and car number 5 is a little different from other general room cars.
However, this excludes KTX-Sancheon, and is limited to first-generation KTX that mainly operates the Gyeongbu Line.
Of course, the price is the same as other standard rooms, but it would be nice to refer to it because you can go a little more comfortably.
