Does anyone remember Hanjin Express, which no longer exists?

I remember the last time I rode it was back in 2005. All the buses were new models, and there were earphones provided in the very front seats, so I remember taking them to use during rest area stops. I believe the company disappeared after being acquired by Dongyang Express the following year. Even though it was just a childhood experience, it remains in my memory as the company with the best service.
