Read and answer.

My name is Hoang Anh. In my free time, I often go camping with my family. The camp is in the forest near Ba Na Hills. We go there by car in the morning. My father likes fishing in the stream. My mother likes cooking barbecue for us. My brother and I usually play hike-and-seek. It’s so fun. We return home late in the evening. We enjoy camping very much.

Question. When do they return home?
