只是梦而已又何必當真
[zhĭ shì mèng ér yĭ yòu hé bì dāng zhēn]
'It's Just a Dream, Why Be Serious?' implies a lighthearted or non-serious attitude towards life's happenings. It’s as if the individual views certain events like dreams—unreal, fleeting moments that needn’t be taken too seriously or dwelled upon.
