I'm ashamed of myself

What you say is true - yán ér yǒu xìn

remain impenitent - hù guò bù quān

from the sky to earth - bì luò huáng quán

smell of orchid all over - fāng lán jìng tǐ

That is to say, to treat people in their own way - jí yǐ qírén zhīdào，huán zhì qírén zhīshēn

not learn even when confused - kùn ér bù xué

be at a loss what to do - bù zhī suǒ kě

confirmed habits are hard to get rid of - jī zhòng bù fǎn

in the dead of night - sān gēng bàn yè

echo one another - cǐ hū bǐ yīng
