We went around 3 p.m., and it was a bit overcast, with soft lighting, perfect for taking photos. The night view of Yuezhao is stunning at night, so if you have enough time, you can stay overnight to experience it all.
The Hongcun Aju performance was fantastic, telling the story of the resilience of Huizhou women. The live performance simulated rain and snow, so you'll need to wear a raincoat or use an umbrella to protect yourself if you're sitting in the front row. After the performance, you can take photos with the performers, and there are international performers, so it's worth seeing.
