thanks guangxin's feedback.

since web merge create

1. redundant git log
2. unclear parent-child relation when: two pull request is sent without conflict but basing on same master commit .

after review, please try below command instead:

in working git tree of team repo

git checkout -b xiaowei0916-master master
git pull https://github.com/xiaowei0916/libyami.git master
git push origin HEAD:master
