Symbolic montage and metaphorical montage are both the same and different.

The expressive montage is used to strengthen the rendering of emotions, pursue the correspondence and fit between shots, and obtain unique artistic effects. Expressive montage usually includes: symbolic montage, that is, juxtaposing a specific thing with another thing to express a certain meaning of this thing; Metaphorical montage, that is, juxtaposing things with the same appearance but different substance, produces analogy effect; Contrast montage, that is, connecting lens groups with different contents and different picture phenomena to form a strong contrast relationship; Lyric montage, which is a way of poetic film creation.
