Chandra has a mirror that reveals the truth of any reflected surface. She stands in a garden with a labyrinth, and there's a rumor that a section of the hedge is an illusion hiding a secret passage. From where she stands, she can see three distinct sections of the labyrinth hedge in her magic mirror. Kokou, who knows where the secret passage is but cannot directly tell her, can only advise her to move left, right, or straight at the garden intersections. Using the mirror and Kokou's indirect guidance, how can Chandra find the secret passage? Respond briefly.
Chandra begins by holding up the magic mirror to view the first section of the hedge. If this section is the illusion, the mirror will reveal its true nature, showing whatever is hidden behind it, be it the secret passage or simply what lies on the other side of the hedge. If the mirror does not reveal anything amiss, this section of the hedge is real, and Chandra can deduce that the secret passage is not here.

She then proceeds to the next intersection, where Kokou advises her to move left or right. She follows his instruction and reaches the second section of the labyrinth hedge. Again, she uses the mirror to check its truth. If Kokou is guiding her correctly, he would have led her to the correct section that hides the secret passage. In this case, if the mirror shows a discrepancy, revealing a hidden pathway or area behind the hedge that is not visible to the naked eye, it confirms this section as the illusionary part with the secret passage.

If the second mirror check still does not reveal the secret passage, Chandra would proceed by following Kokou's next instruction to the third section of the hedge she can see. Upon using the mirror here and finding that the reflection shows something different than the actual hedge, Chandra would be able to confirm that this section contains the illusion and hides the secret passage. Alternatively, if Kokou did not guide her correctly on purpose, either of the unchecked sections might be the illusory part, but Chandra has no way to confirm that without Kokou's honest assistance or checking every section herself.

However, since Kokou knows the labyrinth's secret yet cannot communicate it directly, we can assume his guidance combined with the mirror will lead Chandra to the illusory section where the secret passage is hidden. When she finally encounters the discrepancy in the mirror's reflection against what she sees in reality, she will have successfully located the secret passage in the labyrinth.
