时光已老人心易变
[shí guāng yĭ lăo rén xīn yì biàn]
Translated as 'As time grows old, so do people’s intentions easily change', it carries an air of melancholy about the passing of time leading to changes within people - their thoughts, values, love. This phrase can either express resignation to this reality or disappointment at human nature’s fickleness over time.
