One-on-one education at Xueda University believes that the rhyming memory method of children's songs is to weave the chemical knowledge that needs to be memorized in a phonological way, which is informative and interesting, catchy and easy to remember and memorize. For example, the operation song of pouring the liquid in the narrow-mouth bottle into the test tube: "Hold the label with three fingers of the palm, and the two mouths fall relative to the line of sight." "Three-finger grip" refers to holding the test tube tightly with thumb, forefinger and middle finger; "Eye drops" refers to observing the amount of liquid in the test tube when pouring liquid to prevent excessive dumping.
