左A右B
左A右B pairs two coordinated actions with left and right to depict rapid alternating movement or maneuvering, as in 左躲右闪. The verbs need not be identical, but they must form a coherent parallel action pair. The four-part sequence remains intact and cannot contain aspect markers or misplaced objects.

Read the structure
左A右B pairs two coordinated actions with left and right to depict rapid alternating movement or maneuvering, as in 左躲右闪. The verbs need not be identical, but they must form a coherent parallel action pair. The four-part sequence remains intact and cannot contain aspect markers or misplaced objects. Keep the model 左 + A + 右 + B visible while you compare each sentence.
他左躲右闪，避开了对手。
He dodged left and right and evaded his opponent.
Choose the right context
Use 左躲右闪 for repeated evasive movement. Use established left-right action pairs to depict alternating maneuvers. Place objects and results after the complete pattern when required.
汽车在车流中左穿右插。
The car wove left and right through traffic.
Respect the boundary
Do not omit 右 or its B action. Do not insert aspect marking inside the pattern. Do not put the action's object between 左 and A.
他躲左闪右，避开了对手。
(He dodged left and right and evaded his opponent.)
Repair the pattern
Direction markers follow rather than precede their actions: The construction requires direction-before-action order 左 + A + 右 + B, here 左躲右闪. Aspect marker splits the second direction-action unit: In 左A右B, 右 must directly precede B; aspect 了 cannot split the direction-action unit 右看.
他左躲右闪，避开了对手。
Use the repaired structure without changing the intended meaning.
