It's just that Taiwan opera has been languishing for so many years it lacks new blood. Most of the performers from its heyday are in their forties or fifties and ready to retire, so it's no wonder the actor shortage gives troupe directors fits.
只是歌仔戲長期處於低迷，新血不多，全盛期的老演員又多半已四、五十歲，面臨退休，也就難怪演員荒要令許多戲團班主跳腳了。
