Learning the old testament like a christian.
The Medrash Rabba writes that Yaakov cried because the people around suspected him of pritzus for kissing Rachel. The Seforno adds that this is the reason why Yaakov right away told Rachel that he was related to her so that she too wouldn’t suspect him. The Netziv says a similar pshat on his own, he says that Yaakov cried to show Rachel that the kiss was because she was his relative and was not for lustful purposes. Rabbenu B’Chaye offers 2 explanations, either Rachel was under 3 or that he kissed her hand or forehead and not her lips.
