Against hwei, Stand away from the minion wave so he cannot push and poke you simultaneously.

Abuse his immobile nature by forcing him to over extend, then request a gank and shut him down.

His E is on a really long cooldown. Try to bait it out, and then look to fight him while his only CC tool is on cooldown.
