Honkai Star Rail: How to Find the Portrait of the Singer in the Morning Dew Residence

Teleport to the “Hall of the Dreamlord” anchor, located on the first floor of the Morning Dew Residence (access to this location becomes possible after completing the quest line “Cat Among the Pigeons”), then go through the passage on the left, where the stairs are located. Climb it to the second level, move forward and go through the right door. Continue along the corridor and you will find yourself in a large room with a 3D map.

If you have already visited this place before and activated the bridge, then go to the opposite side, where the portrait hangs. Otherwise, grab the Dream Bubbles from the fountain on the left and activate the bridge just to the left. Walk along it to the wall, then activate the second bubble bridge, which will return you to the horizontal surface.

Then go to the Robin poster and interact with it. As a result, you will unlock the above achievement, for which you will receive 5 star jades.
