Overview概述
Every question in the Kongmu 1 and Kongmu 4 banks, with the traffic regulation behind each answer, built into the app. Practise, review your wrong answers and take timed mock exams without a connection, and without seeing a single ad.科目一、科目四全部题目，每道题的解析都给出所依据的法条原文，全部内置在 App 内。不联网也能刷题、看错题、做限时模拟考，全程没有任何广告。
What is in it里面有什么
The whole bank is inside全部题目内置在 App 内
Every question of the Kongmu 1 and Kongmu 4 banks ships with the app, together with the images. Nothing is downloaded on first run and nothing expires: open it on a train with no signal and you get the same questions you would get on wi-fi.科目一、科目四的全部题目连同图片一起打包在 App 里。首次打开不用下载，也没有有效期：在没信号的地铁上打开，和连着 Wi-Fi 打开是同一套题。
The regulation behind every answer每道题的解析都给到法条
The explanation for each question names the rule it comes from rather than only saying which option is wrong. When two sources disagree about an answer, the app says so instead of silently picking one.每道题的解析会指出它依据的规定，而不只是告诉你哪个选项错了。当两处出处对同一道题说法不一致时，App 会写明，而不是悄悄选一个。
Wrong-answer book and bookmarks错题本与收藏
A question you get wrong goes into the wrong-answer book automatically and leaves it once you answer it correctly; the one you star by hand stays until you unstar it. Both are one tap from the practice tab.答错的题自动进错题本，答对后自动移出；手动标星的收藏题一直留着，直到你自己取消。两个入口都在练习页上，点一下就进去。
Timed mock exams限时模拟考
A mock exam follows the real paper: 100 questions in 45 minutes for Kongmu 1, 50 in 30 minutes for Kongmu 4, with the same pass mark. The result report shows the score, the time used and every question you got wrong, and past attempts are kept so you can see the trend.模拟考按真实试卷来：科目一 100 题 / 45 分钟，科目四 50 题 / 30 分钟，及格线一致。成绩报告给出得分、用时和全部错题，历次成绩会留存，可以看走势。
Practise by type, difficulty or chapter按题型 / 难度 / 章节练
Beside sequential and random practice there are single-choice, multiple-choice, judgement, five difficulty levels, seven chapters, the newest-rule questions and the image questions. Each entry shows how many of its own questions you have done, and reopening one puts you back on the question you left.除顺序练习与随机练习外，还有单选、多选、判断、五档难度、七个章节，以及新规题与图片题。每个入口都显示这一项自己练了多少题，再次进入会回到上次那道题。
No ads, and no connection needed没有广告，也不依赖联网
There is no advertising of any kind, no pop-up, no redirect, no paid content and no account wall. The only thing that ever touches the network is the optional Huawei Account sync, and only if you turn it on.没有任何形式的广告，没有弹窗、没有跳转、没有付费内容，也没有登录墙。唯一会碰到网络的是可选的华为账号云同步，而且只在你主动开启时才会发生。
What it does not do它不做什么
The app is a practice tool, not an official source: it is not published by, endorsed by or affiliated with any traffic-management authority, and the bank is compiled from public regulations and may lag behind the newest rules. It shows no advertising and no paid content. It contains no driving simulation, no video lessons and no community or comment features. Statistics shown are the app’s own count of what you have answered on this device.本 App 是刷题工具，不是官方发布物：它不由任何交管部门发布、认可或与之关联，题库依据公开法规整理，可能滞后于最新规定。它不含广告，也没有任何付费内容；没有驾驶模拟、没有视频课程、没有社区与评论。页面上的统计是本机对你实际作答情况的计数。
