On the June 17th episode of Mnet's 'Beatles Code 2', he revealed, "Promoting as a singer or an actor both have their ups and downs. But as Shinhwa, I work with the members, so even working is fun. When I used to act, others would tell me that singers don't last long. They'd tell me, 'How long do you think you can go on as Shinhwa?' I felt like they were looking down on singers, so I got even more determined."

Dongwan added, "People told me similar things. They told me that you have to focus on acting, so that I should only do one thing. I thought to myself, 'But I don't want to.'"

It looks like both Dongwan and Eric proved whoever told them wrong because they've definitely had a longer career than a lot of actors today.
