Here is a list of combos and mechanics with Xin zhao that i came up with last night. There are a ton more combos but I didnt have the time for it. And maybe in 3 years time when I forgot all the Xin Zhao tricks I can come back and check the downvotes and death threats.
Advanced tricks with Xin Zhao:
Q - Three Talon Strike
Use Q to reset Autoattack timer
-Use Q to kite the enemy. With high attack speed, Xin Zhao can kite melee champions while charginq his Q and lyfestealing
-Sated devourer and Titanic Hydra, combined with Battle Cry, allow Xin Zhao to Reset his cooldowns and knock up his opponents within milliseconds
-3rd Q can interrupt some spells (E.g. broken wings) and basic attacks.
-Charge Q on minions then dash onto the enemy and instantly knocking them up (this ensures the enemy cant blink, dash etc. away) then kill them while they are knocked up
-The ending animation of Q is very long, so make sure you orbwalk your Q
-Use Q (typically on minions) to reduce E cooldown
E - Audacious Charge
-Can be used to dash to minions for an escape
-Can dash onto a minion to slow the enemy with the AOE for an escape
-Can dash over walls by placing a ward over the wall and dashing onto a neutral monster over the wall
-Locking onto the target with E when out of range then following with a flash into range to avoid any downtime
-E an enemy champion while they are mid dash to switch places with them
-Use E as autoattck reset
R - Typhoon
-Ult flash (similar to Lee sin's Kick flash) gives your oponent very little time to react while avoiding any downtime
-_Dragon's Breath:___E onto minion near target to slow them then Ult flash them into your tower or your team
-Autoattck a minion/ward/structure/champion to reset passive and ult the enemy away
-Position yourself so that you can ult the enemy over the wall when escaping. This is much more effective than simply ulting the enemy back randomly, but is hard to pull off
-Use ult to cancel gap closes (E.G. resonating strike). This is extremely difficult to full off.
-Ward mid ult animation to cancel the recoil animation of the ult (And thus animation cancelling). This trick is extremely useful to cancel gap closes.
-Use ''Typhoon'' in combination with flash to isolate a target and assassinate them (This is extremely useful for escaping). One very important trick is to Ult an enemy into your tower and E them to escape the enemy team and get a kill.
-Use R mid E to cancel any downtime (R will activate as soon as you reach your target)

I will add to this post once i figure out his mechanics.
