Hello, I'm an expert in cultural studies with a focus on calendar systems. Let's dive into the question at hand.

The Chinese calendar is a complex system that has evolved over thousands of years. It is a lunisolar calendar, which means it incorporates elements of both the lunar and solar cycles. The lunar component is evident in the way months are defined by the phases of the moon, with each month beginning on a new moon.
