This video can help learners learn the 4 kanjis, 大（big）、小（small）、白（white）、黒（black）without using English.
The current researches show that learners acquire their second language using general cognitive skills including finding out a pattern.
This video clip uses dualistic kanji pairs with related pictures, such as big and small, black and white so that learners can easily guess what each kanji mean.
I use this material for prep to year 2 students. Even if it was the first time for them
to learn those kanjis, they use their own cognitive capability to find out the true meanings.
