Is it better to choose Hongda, Myeongdong or Dongdaemun for tourist accommodation in Seoul, South Korea?

Hongda is more suitable for friends who like to play. There are many duty-free shops near Myeongdong, and there is also a south gate market, which is suitable for shopping partners. Dongdaemun is mainly suitable for small partners who wholesale clothes there, because the market there is generally not retail. You can go to Douta if you want to buy something, but Douta is more expensive.
