After visiting the Nassar courtyard, I entered the Tribune Museum (Tribhuvan Museum). I came out today for convenience, I only brought a SLR and no backpack. I didn't expect to be stopped by the staff after entering the museum door and asked me to send the camera off. So if you come to visit in the future, remember to bring a backpack with your shoulders, put the camera inside, don't bring the camera bag, otherwise the staff will still ask you to send it, or simply bring a card machine. Because, then, when you go up to the top floor of the nine-story tower overlooking Kathmandu, you will regret not having a camera on your hands.
