I quote from the introduction:
"The calculations of general relativity assumed that the light
  passes across the solar surface, which was equivalent to assume
  that the solar radius was a root of the cubic equation. It is
  proved in this paper that the solar radius can not be the orbital
  poles of light. The orbital poles of light were located in the solar
  interior not far from the solar center.

For a star to be blocked by the Sun the star must
be in the ecliptic plane. The Earth is orbiting
the Earth at 1 AU, so when the Earth is at
a straight line from the star through the centre of
the Sun, the star will be behind the Sun.
(The angle star-Sun observed from the Earth = 0⁰)

It is then easy to calculate that if the light should
be bent around the Sun and be visible from the Earth,
the deflection angle would have to be:
  R/AU radians = 0.266696⁰.
But the deflection is only 1.75" = 0.000486⁰
So the star is blocked by the Sun.

Mei's blunder is that he claims that GR predicts
that the deflection is 1.75" when  φ = 0⁰.
That is obviously not the case.
It is easy to calculate that the star will be visible
when     φ < -R/AU rad + 1.75" = -0.2662⁰
and when φ >  R/AU rad - 1.75" =  0.2662⁰
It will blocked by the Sun when  -0.2662⁰ < φ < 0.2662⁰
When φ = ±0.2662⁰ then the light from the star that reaches
          the Earth will graze the Sun.

Mei's gigantic blunder is that when a star in the ecliptic
plane is blocked by the Sun, then:
"the light from stars in outer space would be lost in the solar
  interior and could not be observed by the observers on the earth.
  The night sky on the earth  would be starless."

Mei's confusion is so gigantic that the whole paper
is meaningless drivel even if it may contain some correct math.

Paul, your comprehension is feeble.
No, that is not what he discovered. He pointed out that the
Schwarzschild metric implicitly assumes this.
"Mei's blunder is that he claims that GR predicts
that the deflection is 1.75" when  φ = 0⁰."
Mei points out that Schwarzschild makes this blunder.
You cannot defeat his criticism without addressing the Schwarzschild
metric.
