It means: learning must be extensive, not limited to a few categories, and must learn from the strengths of others.

The original sentence is: Learning must be like a bee, picking many flowers before it can make honey. If it only bites in one place, the income will be very limited and boring.

Bees collect honey layer by layer from the outside to the inside. It inserts small tubes along the bottom of the stamens to suck nectar, and then picks up another flower after picking one. In a pot of flowers, bees usually only pick three or four flowers, and then fly to another pot of flowers.

After picking flowers of all colors, the bees flew back to the first pot of flowers and carefully picked the nectar from the flowers that had already been picked. Therefore, bees collecting nectar is a large-scale and meticulous work.

Mr. Lu Xun taught people that when they study, they must be like bees gathering honey. They must explore other areas and not always linger in the areas they are familiar with. We must learn from others' strengths, be good at pioneering, and become all-round talents.
