First, read the English article below.

Go to https://www.gmail.com/ in your computer's web browser. Doing so will open your Gmail inbox if you're logged into your Gmail account. If you aren't logged into Gmail, enter your email address and password before proceeding. It's in the top-right side of the Gmail inbox. A drop-down menu will appear. This option is in the middle of the drop-down menu. Doing so opens the Settings page. You'll find this tab near the top of the Settings page. It's a link in the "Import mail and contacts" section. Clicking this link prompts a pop-up window. You'll instead click Import from another address here if you've previously imported information from a different email account. You'll do this in the text field that's in the middle of the pop-up window. It's below the text field. Doing so will allow Gmail to find your Yahoo address; when it does, a new window will open. In the new window that opens, enter your Yahoo email address, click Next, enter your email account's password, and click Sign in. It's a blue button near the bottom of the window. This will redirect your focus back to the other pop-up window. It's a grey button at the bottom of the window. You can first uncheck boxes in this window to prevent some features (e.g., importing of new Yahoo email for 30 days). This button is at the bottom of the window. Doing so will prompt Gmail to begin importing your Yahoo mail conversations and contacts.  Per Google's notes, it may take up to two days for new emails to show up in your Gmail inbox. You can close the Settings page without impeding the import process.
