the “X” sound like "sh" in english.

I don't want to be dismissive of others' answers, but they aren't going to help you pronounce the "x" sound in Mandarin. Read the following: There are three tongue positions you need to speak Mandarin. The are broken up by which "initials" (first sounds) they take 1) R ZH CH SH 2) Z C S 3) J Q X For the first set of sounds, you need to put your tongue behind your top teeth on the roof of your mouth. Then, move your tongue backwards until you hit that "ridge" on the roof of your mouth. When the gradient of the roof of your mouth starts to change quite a lot quite quick, that's where you want to stop, just over the ridge, coming from the front that is. That will get you the first position. Say a J to get the ZH sound, say an SH for the sound, a CH for the CH sound and like try and vibrate your tongue against the top of your mouth and get that tongue vibrating for the R sound. It feels pretty damn unnatural at first, but that's right. 2) C S Z - put your tongue on the roof of your mouth just behind your top teeth, make sure your tongue doesn't touch your teeth. This position is the most natural for English speakers. 3) J Q X - this position is WEIRD at first. Put the tip of your tongue behind your bottom front teeth. Then, follow your gum line down, until the tip of your tongue is against the bottom of your mouth and your lower gums. Your tongue should now be in a kind of n shape. Make sure your tongue isn't touching your teeth. For the X, you need to blow like in an SH sound. To start with, you will need to blow REALLY hard as not much air will come out (since it's such an unnatural position for you). The the J sound, you want to have your tongue in the same position and say "J". It will give you a softer thinner J that we have in English. For the Q, say "CH" with your tongue in that position. Again, you'll have to make a deliberate effort to aspirate this sound too. I hope this is helpful. It took me like 4 months to get it down properly. Keep working hard 加油！

it sounds like sh in English,but we prouncing part is more nearer to the front of mouth. you know how to prounce "i" in pinyin? practice your sh + our i

Easy question,maybe most Chinese people have forgot the pronunciation of "pinyin" letters they learnt from elementary school.But I still remember "x" in pinyin letters is pronounced exactly like "c" in English. There is a little difference,if you know the four tones of pinyin letters,"x" uses the first tone,while"c" in English is the fourth tone .
