thanks @HCP
I am a little confused, accoring to your words, if the 12 words seed is invalid I should can not click next button, but I can and cannot get any history and balance

Then you have a "valid" seed mnemonic (12 words)... Unfortunately, it would appear that the mnemonic you have is not the one for the wallet you are attempting to regenerate... so it is generating an empty wallet Undecided

I cannot see any address on "wallet_12345" after finish restore

So you see nothing on the addresses tab? Huh

Try clicking the '>' symbol next to where it says "Receiving"... it should show you the list of pregenerated addresses.

I am sure I record 12 words seed when I am creating wallet, I copy it to my txtfile and use it to restore now.

It seems like you've copied the wrong seed... there is a "quirk" in Electrum... where if you start to create a new wallet -> Standard Wallet -> Create a new seed... and then on the "Confirm Seed" window, if you click back, and go back to the window where the seed is originally displayed, the application will actually generate a completely new seed!

So perhaps you've copied and saved a seed, but then go ahead and created the wallet with a different seed...
OR
You've actually been using a different wallet all along, thinking that you had the seed saved, but it was for a different wallet Undecided
