Chinese does not have an alphabet in the sense that we know it in the West.Chinese characters are not really letters, they are characters that represent concepts and ideas. Enjoy these images. Please subscribe to my blog. 

Pinyin is a Chinese system for transliterating Mandarin Chinese into 25 European characters (the letter “v” is not included).
In Chinese, each character corresponds to one syllable (which corresponds to a part of an English word, and entire word or more than one word). Chinese syllables consist of three elements: initial sound, final sound and tone. The initial sounds are consonants and the final sounds contain at least one vowel. Some syllables consist only of an initial sound or a final sound.
Note that "c", "ch", "j", "q", "r", "sh", "x", "z" and "zh" are spelt differently.

In Chinese (Mandarin) there are 21 initial sounds: b, c, ch, d, f, g, h, j, k, l, m, n, p, q, r, s, sh, t, x, z, zh
In Chinese (Mandarin) there are 35 final sounds:
6 simple finals: a, e, i, o, u, ü
13 compound finals: ai, ao, ei, ia, iao, ie, iou, ou, ua, uai, üe, uei, uo
16 nasal finals: 8 front nasals: an, en, ian, in, uan, üan, uen, ün
                       8 back nasals: ang, eng, iang, ing, iong, ong, uang, ueng
Additional syllables in Mandarin Chinese: 5 special cases: er, hm, hng, ng, ~r

The initial and final sounds make a total of 56 basic sounds. Combinations of initials and finals plus the special cases result in 411 possible combinations. Applying the four tones of Mandarin Chinese to this, we get a total of around 1,600 unique syllables.
