What is particularly helpful is ability, not diploma. Even diplomas from Tsinghua and Peking University will not be of "particularly great help" to students.

If there is anything that will be "particularly helpful" to students, it should be family background and social relations, not diplomas.

As for the universities at the same level as Xi Jiao Tong University of Liverpool, I really don't know what they are and I can't compare them.

Xi Jiaotong-Liverpool University is not a traditional university in China. It has only been established for six years-it is in childhood, so the gold content of its diploma will be covered up.
