Zhin's counter stance will allow him to counter ANY offensive ultimate especially with the counter legendary card. It can even counter torvald's hyper beam, Every hit of Makoa's Ancient rage or any damage ultimate you can think about. Tread lightly
If you are crippled go to counter stance. The enemy will either not attack or if they do you can counter the damage. No matter what this will give you JUST ENOUGH time to escape the cripple and use billow to retreat
When Zhin has his Counter stance up, take the time to reload your weapon, switch targets for a moment, or escape if needed , as you'll be hard-pressed to damage him while he's Countering.
Zhin attacks slowly and his third hit in his attack chain is easily his scariest. His first two attacks deal about 450, where the third deals 700. While not taking damage at all is priority, avoiding that last hit is the most important when fighting.
When you see Zhin is an Opponent, Look at his Legendary. If he isn't using Retaliation, Feel free to shoot his counter from a distance as he will only have one block. Never Shoot a Retaliation Zhin though as most Heal from it... A LOT!
