save against a rainy day

each refused to give in to the other - gè bù xiāng ràng

not cry over the spilt milk - duò zèng bù gù

billions of years - yì wàn sī nián

A trickle of water makes a river - juān dī chéng hé

infringe justice - wéi tiān bèi lǐ

A sick cow - niú yī bìng wò

make painstaking efforts - ǒu xīn dī xuè

I wish you happiness - zhù lù zhù gěng

Knock the ice for fire - qiāo bīng suǒ huǒ

insignificant - fù bèi zhī máo
