Looking for Lo Mein Recipe

https://damndelicious.net/2014/10/03/easy-lo-mein/

I made this lo mein recipe yesterday, but it did not taste like typical lo mein that I could get at a restaurant or takeout. The base and veggies were fine, but I am looking for a different sauce recipe if anyone has any input. I think the ginger was a bit overpowering and and the sauce was not quite as sweet as usual.

Thanks in advance for any input!
