The first one is correct version. However, the two epressions you mentioned are both not native. If you want to say ”I and you have been to Beijing”, you could say in Mandarin, “我们已经去过北京了。” Thanks!
Hey Tracey, did you get my files?
Sorry going through a busy time in office. Yes I analyzed the solution.
It will require some resource, which I could not manage.
Sending you some dough today, you can allocate the resources to this project.
Perfect. Thanks a lot!
I will have them ready by tonight.
