Two months. Every early autumn, wild hazel mushrooms can be seen everywhere in the mountains. According to the local encyclopedia, wild hazel mushrooms in Northeast China can be trampled fresh in July and August. Hazelnut mushroom is the fourth most delicious food in Northeast China. In the northeastern mountainous area in early autumn, I dare not say that hazelnut pickers are everywhere. Anyway, every household goes up the mountain and roadside stalls can be seen everywhere.
