When should you start learning Chinese characters?

When you start to learn Chinese, I suggest to learn the Characters at first, not just learn the pinyin. Learning Chinese characters includes four parts, listening, speaking, reading and writing, involving various content of single character, Word, sentence and article. As a beginner, learning Chinese characters is the foundation. I recommend MagiChinese, an app can help beginners to master the basic Chinese characters quickly, while providing the subsequent learning content of Words and sentences.
