It's worth going, and it's better to invite the commentator, otherwise you just watch, not reward. We went to the Beiling Mausoleum last year when we were a sophomore. Please don't regard it as an ordinary "scenic spot" when we went to such a place. Please be in awe. After all, this is a mausoleum. Some people don't understand the function of burning silk pavilions and even put their heads in to take pictures. I want to say that people should respect history and learn from history. Ancient people could make so many brilliant achievements at such a low material level. We should respect them.
