I read many things about Xuanxuan Qijing but I could not find clear answers to the following questions:

1-What is the estimated difficulty level (average, max, min)?

2-On an SL page, I read that it is more about feelings for vital point. But as far as I interpret the phrase, every L&D problem requires a feeling for vital point, for being able to solve quickly. Then I get confused what makes this one special in that sense. Is it related to the fact that the shapes are commonly seen in real games or should it be interpreted differently?

3-How do you pronounce it?

Thanks in advance

"Unless you are at least top amateur player, some of the problems might show to be almost unsolvable for you"
- Preface to problemset by tasuki

Dan problems for sure. Set is also known as Gengen Gokyo.

Having done the problems in the past, I'd say that easiest problem is probably at strong kyu level, but majority of the problems are in the range of 1-7 dan. Some problems, you could read forever and not get anything. In other words, it should do any strong players good to do the problems just to exercise their reading...

now, with Igo Hatsuyoron...*cries*

Something close to Shwan shwan chee jing ?? - though others may know better, and I don't know about the tones.

Sensei's Library gives the tones as Xuánxuán Qíjīng. Also, Chinese has several different sh sounds, the "x" indicates a sh sound made with the tip of you tongue towards the front of the mouth (as opposed to if it were written "sh", in which case it would be more towards the back). Similarly the "q" indicates a tsh sound, with the tip of you tongue towards the front of the mouth (as opposed to if it were written "ch", in which case it would be more towards the back.) And keep in mind that the "an" at the end of xuan is pronounced like it is in words like "can", "fan", "ran", not like in "swan".

Tricky language

the a's in xuanxuan qijing are closer to the e in Ben than any a's, I think.

Ain't that the truth.

Don't think they are only life&death problems. I remember that, it's not enough to solve the problem, analyses of the problem is important. Because they are not 2-3 moves problems, much deep. And each problem gives you an another view-approach to the go game. They was very important in ancient days.
