I have not help Mr.Wang send a package to Mr.Li by express so far. If I sent the package I will tell you tracking no. 中文背景是: 我没有帮王先生寄过给李先生的包裹.如果我寄了我会告诉你单号的.
时态,语法都有小问题.帮你大改了第一句,强调了重点.第二句,帮你改了时态和连词. I have not sent the package to Mr.Li via EMS on behalf of Mr.Wang. Once I send the package,I will let you know the tracking number.
