All the emails contain a link to a phishing site (seemingly in China) that is set up to harvest Google login details from you and possibly plant Trojans on your computer systems.
If you have visited the site and attempted to login, then make sure you change your Google login passwords IMMEDIATELY!
If all you did was read the mail and think “what’s all this then?” don’t worry no harm can come to you.
This is not the first phishing email and it surely won’t be the last.
Please stay vigilant and keep safe.
