No they are not dating. But Zhang jingyi had an affair with the co-star ( Chen xingxu ) of the drama "fall in love". They were exposed by the media while spending two consecutive nights together in hotel room😂🤣. They had an affair during the filming of the drama and broke up shortly after the filming was over. No one knows why they broke up since the both parties didn't admit about their scandal. Even after going viral they chose to remain silent, perhaps for fear of losing their career.

Fue por edta pareja que me interese en los dramas chinos y en ellos dos ,para mi lo maximo había química tanto de la pantalla la llevaron a la realidad pero que problema con los periodistas metiches arruinaron lo que pudo haber sido una larga relación ,espero que en el futuro se encuentre y retomen su relacion y vuelvan a grabar una nueva película.​@@ONLINE56GAMING

Tbh it’s a measure of Professionalism if you dont fall in love with co actors while working as couple in dramas, it will not lead to good results more often than not. Our Jingyi, if ever she really dated should remain professional and healthy. Cultivating working relationships with all actors she is lucky to work with.
