What kind of Qing land victory could end the Sino-French War

Would a complete Qing victory on land during the Sino-French War change the historical outcome?

Only a victory that destroys the opposing force is likely to end the war; a limited withdrawal leaves France able to keep fighting.

The outcome depends on whether a Qing land victory destroys the opposing army or merely forces it to withdraw. Annihilating the enemy field force would remove its immediate capacity to return and could end the war. A limited victory would instead buy time to repair the Qing fleet while leaving France with much of its fighting strength. In that case, the conflict could continue or pressure could emerge elsewhere.
