be a stranger in a strange land

be poor but ambitious(be poor but proud; Better be poor than wicked.)

a good omen of giving birth to son(a man with a great heart)

Enter a new house

man's heart is incomprehensible(Human hearts are prone to evil.)

Crescent moon

There are plenty of criticisms.

Gentle and sweet

Army and family

Country's propitious portent

Forge ahead forever
