This would prove every number irrational. Without more the fact that X-Y and Y are irrational tells you nothing about whether X is irrational. Indeed it is always the case (as he uses in 2.) that if X is rational and Y is irrational then X-Y is irrational.
We all do stupid things but this paper is so incredibly stupid that part of me wonders whether it is a magnificent hoax. According to Wikipedia, Zhejiang Ocean University exists, so if it is a hoax he has covered the obvious bases.
But these days many university maths departments are useless. Sadly there are plenty of people churning out junk, although most are sensible enough not to claim to have solved notorious long-standing problems.
