To dear friends and distinguished customers:
           Due to the expansion of business, PF’s company mailbox is upgraded from now on. The original domain name（@panjikeji.com）now is changed into the one（@mypanfeng.com）. And the User name follows the old way, which is the Chinese Pinyin of staffs’ name. Please use new email when you contact with us and it’s so sorry to cause inconvenience for you.
