1. Located in the busiest part of Amritsar city center, it is the highest-level Sikh temple; 2. Most of the buildings around the Grand Golden Temple are white, only the main hall in the center of the lake is full of gold, known as "the gem on the Sikh crown" with excellent day and night scenery; 3. Free 24-hour visit to the temple, free shoes, free use of headscarves; 4. Long queues are needed to visit the main hall in the center of the lake. More than 30 minutes, but no photography is allowed; 5. If you don't like to abandon Indian food, breakfast, lunch and dinner are free here; 6. There is a museum outside the temple, mainly a portrait exhibition of important Sikh figures, and the movie exhibition outside the temple is a Sikh story film exhibition composed of four high-tech projection halls built in the underground, all of which are free to visit; 7. If you still feel the above, you will enjoy it. Not enough. I can tell you that there are free water purification, bathrooms, libraries and corridors for visitors to sleep in. That is to say, in theory, you can live in the temple for free forever if you don't get seriously ill.
