The Vietnamese word "cò con" refers to a "petty trader" or someone who engages in small-scale trading activities. It's often associated with individuals who make a living by selling goods or services on a small scale, sometimes without formal business operations. The term can have a slightly negative connotation, implying that the person is involved in minor or unregulated trading activities.
In a more advanced context, "cò con" can be used to describe someone who is trying to profit from situations in a somewhat opportunistic manner. For example, in real estate or other trading scenarios, it can refer to people who flip items or properties for a small profit.
While "cò con" primarily means a petty trader, in some contexts, it can also refer to someone who is perceived as being insignificant or not having much influence in a particular field.
