I didn't see it with my own eyes. Many of them may have been signed by others. Generally speaking, Jolin Tsai took out the bow hook (the longest line in the middle) three times in a row and then made a big arc, which is not reflected at the end here. Of course, it can also be said that the map is fast; But after drawing J, you only drew two circles from top to bottom and then drew an arch hook. The truth is three times. It stands to reason that you have written your signature so many times that you won't miss a circle.
Of course, anything is possible, not to say that you can't see it with your own eyes.
So I don't usually buy anything called a signature. The meaning of the signature is written to you by herself, otherwise it lacks that meaning.
