First of all, let us understand the habits and characteristics of sparrows: sparrows cannot walk on their feet and can only jump. They land and take off quietly, are small and flexible, and have the ability to feed in groups. They have the habit of quickly dispersing and integrating when threatened, forming groups and repeatedly dispersing and integrating to confuse each other and achieve the purpose of feeding.

When sparrows are flying for food, they are mostly in groups of one or two, three or five, or at most a dozen or so, moving east and west, gathering and scattering, with small targets, fast speed, and flexible movements. The guerrilla warfare method created after the way sparrows forage for food is called "sparrow warfare". During the Anti-Japanese War, the anti-Japanese soldiers and civilians often used sparrow warfare, in small groups, moving east and west, looking for opportunities to "pecking" at the enemy, and using this method of warfare to attack the enemy.

Sparrow tactics: It is a kind of breaking down into parts, that is, subdividing the entire war into battles of many local small organizations, and changing the large-scale combat method into a smart combat method. Through repeated dispersion and integration, it confuses the enemy, distracts the enemy's attention, and weakens the enemy's combat effectiveness. Once the fighter opportunity is in hand, superior forces will be concentrated to surround and annihilate it, in exchange for greater results at a smaller cost.

Sparrow wars are mainly fought in mountainous areas. The anti-Japanese army and civilians made full use of the geographical conditions of complex mountainous terrain and rugged roads to carry out flexible and diverse offensive operations against the enemy. If it is discovered that the Japanese and puppet troops have entered the base area, they will fly all over the sky like sparrows, gathering and dispersing at times, waiting for opportunities to attack the enemy. However, the Japanese and puppet troops are unfamiliar with the people and the land. Faced with such tactics, they have nowhere to use their strength and can only passively be beaten. .

At that time, *** mentioned in "Strategic Issues in the Anti-Japanese Guerrilla War": "Generally speaking, guerrillas should be used dispersedly, that is, the so-called 'break into parts' '. "The sparrow tactic is a typical tactic of breaking things into pieces, which fully embodies the tactical wisdom of the anti-Japanese army and people.
