内柔外剛
nai.juu.gai.gou

Literally: inside – soft/weak/gentle – outside – sturdy/strong

Alternately: Acting tough but actually timid. Seeming strong but actually weak. “A lion abroad and a mouse at home.”

Notes: This is a negative saying. It describes bullies, North Korea, and [insert topical political jab of your choice here].

Found here – a blog post that starts out with a good point about leadership and self-examination… but by the end has devolved into an abusive screed about how you are hopeless and helpless without Jesus.
