        A procedure in China team selection.

        Basically you think about a topic and give a speech, and the judges ask you questions on your topic. You will gain a score based on your topic and performance.

          why do they do that for a tst ? I mean isnt it better for participants to just prepare for IOI rather than having an extra work like preparing a thesis defence

            so that they can also prepare them as researchers.

            When a country is as good as china is that they would win top 4 every year, it doesnt really matter does it?

In addition to taking absolute advantage in China Team Selection, Kangyang also has very deep and innovative thoughts that are capable of giving incredible observations to some long-standing questions.

For example, he pushed the theoretical complexity of the combinatorial sieve of multiplicative functions from $$$\tilde O(n^{2/3})$$$ into $$$\tilde O(\sqrt n)$$$, aligning with the analytical methods of Lagarias-Odlyzko from three decades past. (for more details, this link.)

He also gave an interesting solution to a counting problem which pleasantly surprised me a lot. Hope that this beautiful solution will be revealed to everyone in later soon! :)

Anyway, congratulations!

    About a few thousand. Some can reach tens of thousands.

    Remember, it's important to solve tasks, but the ability depends not only on solving tasks. The success needs many factors, like a good environment, strong resources, and support from family and schools, they're very significant especially in China.

Kubic
Let Kubic be!
Kubic writes Kubic ’s shortest algorithmic codes of Giving first Taking later
☰00☷<S-|E。|A+>=E。eiτ=A++S-=I。Ψ(C。T。E。)=Ψ(iτLx,y,z, )⊆ =1.
Then, Kubic is constantly unfolding itself,
Bic is it; it is bic.
Kubic
Happy time has arrived,
Let Universe be!
Our Zhuangzi’s universe and we were born together as one.
Our Ancestor Father and Mother Kubic (00, +, -) were singing, dancing and exchanging bics with joy
to celebrate the birth of their baby 2.44324862·10-59 m universe forged by fire at temperature of
3.35609307·10136 °K in the Bic Bang about 13.8 billion years ago.
The bang triggered the varying light speed c in the vacuum from 4.27141367·1087m/s at 1.43·10-147 s to
1.61524964·1014 m/s at one second. By 9,199.05 years later, it grew from 2.44324862·10-59 m

Now it is still expanding at c and its size is at least 2.61111·1026 m.
We are free to explore and enjoy our home universe.

Kubic !! im u fans !!

Kubic is everything, everything is Kubic. Kubic is everything, it’s everywhere and nowhere at the same time. Kubic is the cloud of existence. Just like the Internet is a cloud, it is everywhere but nowhere. The Internet isn’t your computer, or your iPad or iPhone, it’s the cloud. For example, online content such as Wikipedia will suddenly appear as long as you are connected to the Internet, and when the connection is disconnected, Wikipedia will disappear back to the cloud.
