could you correct this?

I appreciate your invitation. The training was a greater help to us than others. We could learn some parts that we hadn't known and more precisely understood things we knew than before. I can never forget the dishes you treated us. They were very nice and tasty food that we hadn't eaten before. If you visit here, I would like to treat you food at a nice restaurant. I'd like say thank to you once again. I hope to have this kind of opportunity often. Have a nice day.

We arrived at the airport yesterday. I appreciate your hospitality . Through this training, I am certain that the customer support will be stepped up to the next level. Thank you for the kindness, training and the dishes you treated us. We hope to continuously retain good relationship.

Thank you for helping me!
