Contact Andrew Yu

There are many ways to contact me. None of these require proprietary software.

• Talk to me in real life. For those at the Songjiang Campus: I'm often in the library at noon time, before tutor time that is. I'm often on the tracks during MW3 and at Neuroscience (N201) during TT3. I'm usually in E104 from 21:00.
• Electronic mail to andrew AT andrewyu DOT org. (Please sign and encrypt messages. See below.)
• Paper mail to Yu, Andrew (Run Xi 于润熙, s22537), 1800, Lane 900 North Sanxin Road, Songjiang District, Shanghai, China 201620. (Note that I do not check school mail daily and I can't check it during vacations. Please do not attempt to use OpenPGP encryption or similar encryption for paper mail.)

Please do not contact me via WeChat.

I do not use popular social media like Twitter or Weibo.

OpenPGP

If you have no idea what these mean, read the Email Self Defense tutorial.

Usually, electronic mail that I send are signed with my OpenPGP key. Please use OpenPGP when contacting me through electronic mail. The following are available.

• My ECC key (recommended)
• My RSA key
• My keyring of friends

In order to verify the authenticity of the key, check if you've actually downloaded these keys from andrewyu.org, and also check the fingerprints with me elsewhere (email, IRC, in real life, etc) before trusting or signing it.

Once confirmed, please sign and share my key in order to build the OpenPGP Web of Trust.
