Purchased an entry ticket with explanation at Ctrip, and then I had a guided tour person there?
Explainations, referring to historical records, decipher artifacts from their very essence. In their very essence, artifacts are nothing more than relevant to life and events in history, signifying that they have borne witness to a series of historical occurrences.
Recommendation: Choose 2 hours, it’s the same as choosing 3 hours.
Translated text:

Chose three hours of explanation, it already feels quite packed. Just take a moment to pause and snap some photos before having to go find the guide again.
Two hours are enough, explaining the main exhibits and you can take a closer look at other similar exhibits on your own. Of course, if there are fewer visitors, three hours of explanation would be even better.
Two hours cannot explain everything, it’s best to go inside the museum and take the guided tour within the museum.

Two hours can’t tell, it depends on the instructor’s level.
I think three hours is quite suitable, speaking in a more detailed manner; two hours might be too rushed.
Self-rent a guide and stroll around is pretty good; no need to explain, it’s very different from interacting with the tour guide.
There’s no big difference, it all depends on the guide. The unique features of this library can be introduced well enough that would be quite nice already; however, the staff from Ctrip’s explanation company are far too low-level.
We gather at 9:30 am in the morning, first going to the restoration hall and then heading to the exhibition hall.
If interested in humanities, I would still highly recommend a three-hour explanation. Highly recommended.
The official explanation of the museum is 90 minutes, actually two hours’ worth can be enough.
Purchased an explanatory ticket on Ctrip, and upon arrival at the scenic spot is there still a human guide?
Translation:

“Exposition is based on historical records to interpret the artifacts themselves. The artifacts themselves are simply closely related to daily life, and their significance is that they bear witness to historical events.”
Recommend choosing the 2-hour one, and it’s the same as the 3-hour one.

Two hours can’t finish, it’s best to go into the museum and ask for an on-site guide inside.

Two hours cannot finish, it depends on the lecturer’s level.
I think three hours is more suitable, it covers the main points well, two hours might be too rushed.
It’s pretty good to rent a guide and just wander around, you don’t need an explanation, there are many guides.
No big difference, it all depends on the guide. The distinctive features of this museum can be introduced by them anyway, and that’s quite good enough, but the staff from Ctrip who provide explanations are too mediocre.
We gather at 9:30 in the morning. First, we went to the museum of repair. Then, we went to the exhibition hall.
If interested in humanities, I would highly recommend a three-hour explanation, and it is highly recommended.
The official museum guide is 90 minutes, which has actually already been enough.
