Sorry for the delay but work is a bit toxic. As promise, here’s a 3-day itinerary should you wish to visit Henan Province from Beijing. Feel free to use this as reference on your trips and if you have any other suggestions, please leave some comments for others to see.
Brief background: Henan province is in Central China. 河南 literally translated to English as “South of the River”, was the core area of ancient China for the first half of Chinese history. It is also the most populous province in China by residency. Henan province has temperate climate for China standards. IMO, best time to visit would be late Spring or early Autumn.
