morning, dynasty, regime, epoch, period, (North) Korea
朝 centers on the early part of the day: morning. Its extended meanings of dynasty, regime, or epoch come from the idea of a ruler holding court in the morning, and the (North) Korea sense is a specific application of that political meaning.
朝 originally depicted the sun (日) rising through vegetation (the left part, originally 艸) beside the moon (月), representing the morning. The political meanings later extended from the idea of the morning court audience.
The left side looks like the sun (日) rising through plants (十), and the right side is the moon (月) still visible. Together they show the moment when night meets day: morning.
For チョウ, imagine a morning court session where the ruler is addressed as 'Chou' (a made-up title pronounced 'choh'). The morning audience with Chou helps you remember チョウ.
