"How did you manage to find me even though I only know Engpsh?" is a common way to express the idea that you are surprised or impressed that someone was able to locate or contact you even though you only know Engpsh.

The phrase "how did you manage to" is a way of asking someone how they were able to do something, often when it seems difficult or unpkely. For example, "How did you manage to finish the project on time?" means "How were you able to finish the project on time?"

The phrase "find me" means to locate or discover someone's whereabouts. It can also be used more generally to mean to discover or uncover something.

The phrase "even though" is used to introduce a contrast or exception to what has been said before. For example, "I usually eat healthy, but even though I was really hungry, I didn't want to eat the greasy food that was available." This means "Although I usually eat healthy, in this particular situation, I didn't want to eat the greasy food that was available, even though I was really hungry."

Here are some other examples of this phrase in different contexts:

"I'm surprised you remembered my birthday, even though we haven't talked in years."
"How did you manage to get tickets to the concert, even though it was sold out?"
"I'm impressed that you were able to find the right exit, even though the signs were all in a foreign language."
