+## Support For zh_CN
+
+Yes, now, from version 0.0.5, it can use template contains chinese characters :tada:.
+
+Just pass argument `zh=True` when creating a Journalist(), or set its `zh` property at any time before generating reports. 
+
+```py
+reporter = Journalist(template_file='./reports/template.md', zh=True)
+```
+
+If you want to use your customized template with chinese characters, don't forget to add one line at first of the YAML metadata block in your `Markdown` template:
+
+```markdown
+---
+documentclass: ctexbeamer
+...
+---
+```
+
+Here is a [simple example](./examples/3_zh_CN_support.py) similar to [Quick start](#quick-start), Except for [its template](./examples/reports/3_zh_cn_template.md) containing chinese characters. A perfect chinese [slides](./examples/reports/3_zh_report.pdf) file can be generated by the program as:
+
+![](./demo/zh_demo.png)
+
+**Note**: make sure `xelatex` is installed properly.
+
 ## What will my variables on slides look like?
 
 All variables pass to `Journalist` via `hear` will display as strings just like what their `__str__` method does.
