Hope you're going well.
Thanks for your confirm but I just wonder who should be the contact person when we inspection at there?
As you well know that the contact person could communicate in English so can you please ask for some one in factory to take care on this issue?
And let me know him/his e-mail address by next mail. (also cc in the loop)
For factory car that will come to pick us up on that day, It would be more easy if you can let me know the car number or show us a signboard with my name when he's arrived the hotel.
