It's no use telling you anything. Don't believe this and that. How can it be useful? Recite a word indefinitely until you remember it, change it to the next one, and then connect it with the last one after memorizing it. Recite it again and then group it after dozens, so that it will increase. Every day you review and learn new things. It's no use reciting, but if you can read on, it will deepen. You forget history and remember how to spell it.
