Hi Shengli,
   Nice slides. Please consider my following comments -- with these
included I sign-off.

slide#2:
"Deformation has negative contributes on
correlation between v2"
-->
"Deformation has negative contribution on
correlation between v2"

slide#5:
I am not sure how to modify this sentence about Pearson coefficient. It
contain boths three particle and two-particle correlations (in numerator
and denominator). Currently the sentence is a bit ambiguous.
Probably we can write:
"Pearson coefficient: designed to measure dynamical fluctuations"
or
"Pearson coefficient: designed to eliminate statistical fluctuations"

slide#11 and other titles where you write "compared with"
"Compared with TRENTo initial condition model"
-->
"Comparison with TRENTo initial condition model"

slide#12 and everywhere:
Let's choose one of this: "A hierarchical" or "An hierarchical"

slide#13:
"AMPT can do a more precise calculation due to large statistics"
-->
"AMPT allows more precise calculation due to large statistics"

slide#14:
Can you please move the labels like "STAR 0-5.0%" away from the red
band. You an put them either above  or below to improve clarity.
Please put U+U collisions somewhere in the plot. I am not sure we need
to put "STAR preliminary" on each plot -- probably not.

slide#14:
"with three model"
-->
"with three models"

slide#14:
"central region"
-->
"central collisions"


slide#14:
"First time to extract the quadrupole deformation at extremely short
time scale (<10^-24s)"
-->
"First extraction of quadrupole deformation at extremely short time
scales (<10^-24s) of heavy ion collisions"

slide#15:
"A sign change is observed"
-->
"A sign change of v2-pT correlation is observed"

"Non-flow has been study vis"
-->
"Nonflow has been studied via"

"central region"
-->
"central collisions"

"comparing with several model calculations"
-->
"comparison with several model calculations"

"indicates the β_2"
-->
"constrain β_2 in the range of 0.2-0.4 for Uranium"


"First time to extract the quadrupole deformation at extremely short
time scale (10^-24 s) by heavy ion collisions"
-->
"First constraints on quadrupole deformation of nuclei at extremely
short time scales (<10^-24s) accessible through heavy ion collisions"


Best,
Prithwish
