Problem description

if inscribe
Every time I prepare to push, I feel more troublesome. Is my opening method wrong?
After my local build or commit
Then tag it and bind it to a distant hub.
Then push
As a result, the local area will show two local ones of the same size and a remote one, “did the remote one also pull to the local area?” 」

Is that the next time I hit a tag, push it, and add a local+remote?

When building, the tag should be typed well. these two are the same mirror image, but the name or tag is different. there is no need to divide them into two steps.
