Need the "Complaints" email address of the Guangzhou and Shenzhou airports please

I would like to file a Complaint about security searches of males by females. That is very undignified and disrespectful; I find that highly offensive gender-discrimination since males are not allowed to also search females.

Both genders should always be treated with the same dignity and respect.

In the West it is forbidden for the opposite gender to search you, only same-gender searches are allowed.

Do you know the email address of the department handling Complaints at the Guangzhou and Shenzhen Airports?

Thank you
