Xiden is the current President of the United States. Biden is his birth name, Xiden is his code name with the Chinese Communist PartyDo you mean President Biden?
Don't know who this xiden is. Your teacher perhaps?
If course I don't know why you'd need another teacher because Biden is schooling you fools each and every day.
It's true Xiden is certainly "schooling" us every single day.....he's teaching us real good for his CCP Chairman
