They write the words with hot liquid chocolate on the upper surface of a cake and then they eat it.

Hi Egor, I owe you a serious answer! I have been using flash cards for learning Chinese words; flash-cards are like playing cards, maybe a little smaller, that you make out of cardboard. On one side you write a word or a small sentence in language A, and on the other side you write the same meaning in language B. You always carry a deck of playing cards in your pocket, and whenever you are idle, like waiting for the bus, you just use mix them up, them as a teacher asking questions. It seems childish, but please believe me, it's fun and also helpful. Of course you might write grammar questions and whatever; what happens is that after a while you keep the 'easy ones' at home, and keep carrying with you the 'hard ones'.

Maybe with songs. :/

Basic repetition and using the words everyday. Also, relating them to your language or similar words help! Hope this helps^^ Have a nice day!
