四季清秋

'Si Ji Qing Qiu' literally means 'Four Seasons Clear Autumn'. While this phrase itself seems contradictory, as autumn doesn’t last through all four seasons, its meaning can be derived more metaphorically. 'Clear autumn' is usually associated with a cool refreshing breeze, so the whole expression might refer to keeping an elegant or tranquil mindset amidst life’s changes across time, or staying clear-hearted year around.
