Add sougou pinyin thesaurus in fcitx's thesaurus.
Download these two .mb files, copy them to /usr/share/fcitx/pinyin and restart fcitx.
Use this thing:scel4mb, download a sougou pinyin thesaurus， enter the scel4mb directory, execute ./sgscel2fcitx YourThesaurusPath, then, execute cat sg_pyPhrase.org >> pyPhrase.org and ./noOverlap, the latter command may take too much time, don't worry, just wait until it finishes. At last, there will be a new file named tmp.txt, remove sg_pyPhrase.org and pyPhrase.org, rename tmp.txt to pyPhrase.org, if you have more thesauruses, do those things again until you add everything into pyPhrase.org,finally, execute ./createPYMB gbkpy.org pyPhrase.org you wil get two files with the same names in this repository.
you may need libXft.so.2 ,it is provided by lib32-libxft in Arch Linux, other distributions may have similar name.
Add these sougou pinyin thesauruses in these files:
下载这个仓库里面的.mb文件，复制到/usr/share/fcitx/pinyin然后重启fcitx就可以了
使用这个工具：scel4mb，下载搜狗拼音的细胞词库，进入这个工具的目录，执行./sgscel2fcitx 细胞词库位置，之后执行cat sg_pyPhrase.org >> pyPhrase.org 和 ./noOverlap ,后面一个指令会要很长时间，等它处理完，之后移除sg_pyPhrase.org和pyPhrase.org，把新生成的tmp.txt重命名为pyPhrase.org，如果还有其他的词库，重复以上操作直到一切都弄好了，最后执行 ./createPYMB gpgkey.org pyPhrase.org 这会得到类似的两个.mb文件。
缺少libXft.so.2时在Arch Linux下安装lib32-libxft，其他Linux发行版请自行查找相似软件包。
这个项目的文件加入了以下搜狗拼音细胞词库：
