I haven't seen this wild vegetable for decades. How can I make friends?

I really like digging wild vegetables in the mountains. I'm exhausted after digging for two hours, and I feel thinner than any exercise.

Spring is the season for the growth of wild vegetables, and the wild vegetables naturally growing on the mountain are undoubtedly the most suitable for digging. However, it takes a lot of physical strength.

The growing environment and process of wild vegetables picked by citizens in the wild (including residential green space) and parks are uncontrollable, and the "life experience" is not as traceable as that of artificially planted vegetables, so there is a great safety risk in eating them.
