The greatest attraction of the religion established in 1926 is the Great Cao Dai Temple, whose fabulously colorful interior and prayers made an amazing impression on me. On the other hand, a visit to the hundreds of kilometers of Cu Chi tunnels from the Vietnam War was an instructive history lesson. Although the sightseeing was interrupted by a heavy downpour, I managed to test several dozen meters through narrow and winding corridors, which turned out to be an extremely exhausting task.
