In Chinese, different characters or 字,can sound the same but with different meaning altogether. So Jing can have 3 different sounds depending on the tone. It can be jīng,jǐng and jìng,but never jíng because no such Chinese character exist. It is pronounced as dz(j)ee-ng depending on the tone. It can be of any character, such as 静(silence), 京(the capital), 净(clean), 晶(crystal) etc. For me my given name is 璟,which means the luster of jade.
