Dear Sir:


Recently, I obtain a strange picture about HWCC and I can't tell about whether it's nontrivial or trivial. For the one hand, white circle clearly show about its trivial topology. For the other hand, Blue circle did go through the white circle for five times and testify its nontrivial topology. Can you give me some advices? PS, the system doesn't have a time reversal symmetry.
Have a nice day.





Best wished,
Ning Mao
