We carry on as always... I would say
also we go on as always

..vielleicht?

We keep going / carry on as usual.

is correct, not "as always."

We are going to keep doing it as we always have.
We will do it the same way we have always done it.
We're going to keep doing it the same way we've been doing it.
More of the same.

OT: Hanzi, do you speak Chinese?

Context is necessary if you really want some help. I think the tense of the versions suggested so far should be changed.
e.g. We'll carry on as usual

As said, without context it's anyone's guess.
But forget "we go on as always" (#1), which is rather strange.

It may not make a difference here, but strictly speaking, "bisher" is not the same as "always."

Yes, and isn't "Wir machen so..." present for future so to speak?
So maybe "We will carry on as usual." ?

Carry on is possible in AE, but it sounds a bit BE, perhaps as if an activity was interrupted and now that the interruption is over, the activity should be resumed. That is, get back to it, or maybe keep slogging.

Strictly speaking usual is not the same as bisher either.
