In study and work,
No matter how good we are at a few things,
So it was praised by others,
To show humility,
They will say that I only know a little bit, I only know a little bit.
As often said, "a little bit of knowledge",
It's easy for us to look at the literal righteousness,
Translate it as know a thing or two,
In fact, this is a wrong understanding.
a thing or two
Indicate some facts, some knowledge.

Of course, I figured out the ins and outs of things.
It's about mastering something.
例1：the economist's language expert, lane green, knows a thing or two about english.

例2：he would know a thing or two about integrated circuits. he co-founded a great company in 1968.
