The teacher regards every student as if they were her own.
Tips
usage
Most often used for stepchildren, adopted children, nephews/nieces, or students — any non-biological relationship where the elder treats the younger with full parental devotion. Strong praise; not used lightly.
memory
视 (to regard) + 同 (the same as) + 己出 (born of oneself): four characters that literally spell out 'see them as if they came out of me'.
