I'm all over the place

not even a blade of grass grows - cùn cǎo bù shēng

not choose at random - nìng quē wù làn

pull up enemy flags and behead enemy generals on the battle field - qiān qí zhǎn jiàng

dearer than one 's own flesh and blood - qíng yú gǔ ròu

a fish leaping over the dragon gate -- have passed a competitive examination - yú shēng lóng mén

cut off communication with the outside world - bì kǒu què guǐ

Spit, feed and stop washing - tǔ bǔ chuò xǐ

turn from a guest into a host - fǎn kè wéi zhǔ

Desheng first time - dé shèng tóu huí

I'm not familiar with my life - rén shēng lù bù shú
