I don't know if you want to insert a dynamic diagram or sign it. If you just add a dynamic diagram, it will be very simple. Go to Baidu pictures and search for an animation in GIF format. If you like, click the right mouse button and copy it. Go back to the post bar and talk. There is a column where you can insert pictures, select them, and then click the right mouse button to paste them. It doesn't matter. If you want to make a signature post, then you go to /f? kw = % CE % D2 % BB % B3 % D2 % C9 % C0 % B4 % B5 % BD % D5 % E2 % B8 % F6 % B0 % C9 % B5 % C4 % C8 % CB % B6 % BC % D3 % D0 % C9 % f 1% BE % AD % B2 % a 1 & amp； From=loginbar someone will do it for you. I hope what I said can help you.
