The thinned Jia Ling has been widely loved and concerned.
Jia Ling's emotional intelligence is very high, she can be a maverick, and she is deeply loved by the majority of fans. Her sincerity, straightforward and unpretentious character, as well as her love for comedy, make her an existence that men like and women don't envy. Although it is now popular to be thin for beauty, Jia Ling is not very fat, and can even be said to be plump, and many boys like this type of meat. 
Jia Ling's image has been significantly improved, her temperament has changed greatly, and her appearance has increased significantly. This change may further attract the attention of more guys, especially those who appreciate her personality and talent. However, the answer to the question of whether someone would want Jia Ling to be his girlfriend may vary from person to person. Everyone's preferences and values are different, and some people may like Jia Ling because of her personality and talent and are willing to build a deep relationship with her. But it is also possible that some people don't like Jia Ling very much because of other reasons (such as appearance, figure, etc.), or will not consider her as a girlfriend. 
Therefore, it cannot be generalized that all boys will like the slimmed Jia Ling, or they will want her to be their girlfriend. Although Jia Ling's image has improved, everyone's preferences and values for their partners are different. Some guys may be attracted to Jia Ling's personality and talent, find her funny, sincere, and unpretentious, and are willing to build a deep relationship with her. And some boys may pay more attention to appearance and figure, and are not too interested in Jia Ling's plump image, or will not consider her as a girlfriend.
In addition, Jia Ling herself may not want her love life to be paid too much attention and evaluation. She is an independent, confident woman with her own pursuits, and may be more focused on career and personal growth. Therefore, we should respect Jia Ling's choice and privacy, and not judge and interfere too much in her personal life.
In general, the thinned Jia Ling has been loved and paid attention to by more people, but this does not mean that all boys will want her to be their girlfriend. Everyone has their own preferences and values, and the choice of a partner will also vary from person to person. We should respect everyone's choices and privacy, and refrain from judging and interfering in the lives of others too much.
