Thank you, 

Actually, it's a bit advanced to learn from the video. I'm still a beginner. So I tried once again and the message I'm getting is this: 'Properties of base fields cannot be altered in this manner! Please modify them through Python code'

So I tried to work it out from View Field to find "name" then Edit View:Form in this line  but there was an error, lengthy one. I didn't know what it means. 

Hi,

When the translate attribute is set to true, it makes the field translatable. Depending on the user interface language, it can hold different values. so you need to create a custom module and inherit the model that you needed the translation and add this attribute ,Try this example

name = fields.Char(string="Name", translate=True)
