11 | If you open a text by VIM which contents are json lines text, such as:
12 | 
13 |     {"question": "\u53d1\u5458\u5de5\u7684\u4e1c\u897f", "choices": ["\u6781\u6b63", "\u504f\u6b63", "\u4e2d\u6027", "\u504f\u8d1f", "\u6781\u8d1f", "\u975e\u8bc4\u4ef7"]}
14 |     {"question": "\u6613\u8fc5\u8fd9\u6837\u6ca1\u6cd5\u6bd4", "choices": ["\u6781\u6b63", "\u504f\u6b63", "\u4e2d\u6027", "\u504f\u8d1f", "\u6781\u8d1f", "\u975e\u8bc4\u4ef7"]}
15 |     {"question": "\u5f88\u591a\u4e1c\u897f\u5df2\u7ecf\u6bd4", "choices": ["\u6781\u6b63", "\u504f\u6b63", "\u4e2d\u6027", "\u504f\u8d1f", "\u6781\u8d1f", "\u975e\u8bc4\u4ef7"]}

17 | These json lines are inconvenient for human to read it, because of formating and encoding. Using this plugin, you can read these lines easily!
