guanxi - the idea of relationship that is extremely powerful in this culture. This type of relationship can open doors that were previously closed. When you know someone, they can override the system in your favor. Or if you don't know someone, you can kiss your chances of anything happening goodbye. Who you know, not what you know.
cha bu duo - more or less, directly translated. But it actually stands in for a variety of ideas. You can use this phrase to communicate that somethings is kinda true, or almost the right amount, or probably about fixed. In my home culture, we value truth and facts. That exactly the right amount of food is in the container and the car mechanic did exactly the work we agreed upon. Here, things are more or less. You just kinda go with the flow. Don't make a fuss. Even this definition I would say is cha bu duo right. Ha. Proving that my mind no longer functions in exclusively Western norms and standards.
I'll keep an eye out for some more examples.
