Learning Chinese is not the easiest things to do because it involves learning different strokes and tones. One particular word with different tones can result in something completely different. Even with same tone,same pinyin that does not mean it will be the same Chinese character.
Luckily, in Chinese, there are only 4 tones, sometimes there is the 5th tone, called silence tone. For example, in pinyin, Wen with first tone, means Warm. Wen with second tone means Smell.Wen with third tone means Kiss. Then Wen with four tone means Ask. Who would of think of a word with different tones can become another new word. In English, there is no such thing as “Tone”, which makes very easy to learn, except grammar. Then in Chinese, there is no grammar to learn, just some simple rules.
In order to write the correct Chinese character , one must memorize all the strokes. In missing one stroke, a character might of turned into something very differently. I believe this is one of the biggest problem for foreigner to learn Chinese. I have asked few non-Chinese speaking students in my Chinese class, they have agreed these are their major concern in learning Chinese. However, acquire new skill take times and LOTS PRACTICES. Not only in writing, but practice to say words out loud enable learners to improve their Chinese skills with great result.
