What about SAP?

SAP and Ctrip can't compare at all. If there is an internship opportunity for SAP, you must seize it. At present, SAP is the third largest pure software company in the world, second only to Microsoft and Oracle Bone Inscriptions (after the merger of Oracle Bone Inscriptions and SUN, it is no longer a pure software company, and Microsoft also merged with Sun). SAP's enterprise management solution with ERP as the core is definitely the first in the world. For the description of SAP, please see its official website. There are many online contents, so I won't repeat them here. But it is not easy to join SAP, which is much better than Ctrip.
