Character breakdown
Study each Hanzi separately, then return to the complete word so pronunciation, meaning, and movement stay connected.
How to learn 二硫键
Listen once without reading, repeat the pinyin with its tones, then write every character in sequence. Finally, recall the complete meaning instead of memorizing each character as an isolated translation.
When the word appears in a sentence, check whether its part of speech and meaning match the definition shown here. Chinese words can change nuance with context.
