create wordcloud with chinese
=============================

Wordcloud is a very good tool, but if you want to create
Chinese wordcloud only wordcloud is not enough. The file
shows how to use wordcloud with Chinese. First, you need a
Chinese word segmentation library jieba, jieba is now the
most elegant the most popular Chinese word segmentation tool in python.
You can use 'PIP install jieba'. To install it. As you can see,
at the same time using wordcloud with jieba very convenient
