早安，午安，晚安
Good morning, good afternoon, good evening.
一條直線，無事發生
is a straight line, where nothing happens.
This phrase carries deep contemplative undertones, drawing a parallel between the simplicity of daily greetings and the tranquility of a peaceful life. The concept of "safety" or "peace" depicted as a straight line is a profound reflection on the stability and serenity of an uneventful life, suggesting that sometimes, the absence of events is the most desired state of being.
