I admire you so much that you can join the open source community at a
very young age. I will continue to offer my help both online and
offline, in your favorite language (Chinese of course).

There are too many differences between English and Chinese, but don't
worry. Remember, practice is perfect. You can also practice your
English by reviewing Git l10n in Chinese, see: "po/README.md".

Git objects are stored in ".git/objects" directory in two forms: loose
object and packfile.  These two types of files are deflated in zlib
format. In order to increase the speed of traversing these objects in
this object store, many meta files are created. For example, index
files and reverse index files for packfiles, bitmap file, commit-graph
files, etc.

Docs for these files:

 * Documentation/technical/pack-format.txt
 * Documentation/technical/index-format.txt
 * Documentation/technical/chunk-format.txt
 * Documentation/technical/multi-pack-index.txt
 * Documentation/technical/bitmap-format.txt
 * Documentation/technical/commit-graph-format.txt
 * Documentation/technical/commit-graph.txt
