The Cantonese Pronunciation of "Busy"

What are the Cantonese pronunciations of "Mangzhong" and "Zhong" in "Mangzhong", one of the 24 solar terms in China? 1. The "busy" sound of light? 2. The "Meng" sound of mango? 3. The "total" sound of seeds? 4. The "vertical" sound of planting? Can you enlighten me? -it is "busy".

The word "awn seed" literally means "wheat with awn can be harvested quickly, and rice with awn can be planted" (zh. * */wiki/%E8% 8a% 92% E7% A7% 8d)。
