Wu Geng Lin Arron's birthname. Whenever fans shout his name on official events, he feels strange and awkward.

Yan Ya Lun Arron's Chinese screen name.

Ah Bu Arron's nickname since high school. According to his recent photobook, his friends nicknamed him after Kobe Bryant, Arron's favorite basketball player. (Bryant in chinese is pronounced as 'bu' something in mandarin, can't read the whole name in chinese.) At the same time, Ah Bu is also Arron's character name in It Started With a Kiss.

Xiao Lun Lun or Lun Lun Some of Arron's fans call him this way. According to Arron himself, this nickname made him get goosebumps.

Huo Huo Arron once all himself 'huo huo' on one of his blog entries. His surname 'Yan' is a combination of two 'huo' so he separated them and thus became 'huo huo'

Jack This is Arron's original english name. When he went to America because of his father's work, he was on the plane to the USA and watched a movie with the main character called Jack. Although he forgot the title, it was so sad that he cried. It made such an impression that he was called Jack while he was in the States.

Aaron His english screen name and this is how his name is officially spelled. However, he sometimes spell his name as Arron, so both are acceptable. (I personally prefer spelling it Arron :) )
