I personally think that Wang Qingxing sounds better than Wang. First of all, the word "Hangzhou" is more unique than the word "Han" in phonology, with clear pronunciation and a sense of atmosphere and publicity. Although the word "Han" is also a good word, its pronunciation is relatively dull and not as strong as the word "Hangzhou". Secondly, the name combination of "Youth Airlines" is unique, unusual and sounds novel. On the contrary, the name combination of "Han Qing" is more common in real life, which may sound a little ordinary.
Of course, this is only a personal subjective feeling and does not represent the views of others. Everyone has his own unique feelings and evaluation criteria for the pleasant degree of a name, so there is no absolute answer.
