原来只是扯淡
[yuán lái zhĭ shì chĕ dàn]
'Yuan lai zhi shi chi dan'. This means 'Turns out it was all nonsense' or 'Turns out we were just shooting the breeze'. It expresses an attitude toward finding out after certain happenings that some things or previous experiences weren't as significant or meaningful as once thought, but rather frivolous.
