While playing classes that dash or engage, focus on timing a dodge before Feng dashes at you, then counter him with your own. It's generally pretty predictable because he'll line you up. For instance if playing Kallari, use RMB (if necessary) to dodge it then R and fight.
Dodge and weave try to get away from him because of how effective he is at a close range. Also, to counter him use a burst range ADC to counter pick him. If you cant do this and he comes in close proximity use and ability or blink card to get out of there.
