Mount command can not contain Chinese characters
Try escaping the unicode

图片 translates as  %E5%9B%BE%E7%89%87 using an escape function I found online at http://www.url-encode-decode.com 

The app UnicodeChecker installs a service which can convert any unicode character string into percent escapes.

See https://stackoverflow.com/questions/912811/what-is-the-proper-way-to-url-encode-unicode-characters for a reference.
