山盟海誓不及一句我养你
[shān méng hăi shì bù jí yī jù wŏ yăng nĭ]
'Promises made at high mountains and vast seas cannot match a sentence: I will take care of you'. This indicates the promise that words from deep emotions and heavy commitment fall short of practical action - supporting another economically. It reflects the importance placed on providing material guarantees compared with abstract vows or pledges of love in a relationship context.
