The word "playb" means that the first method doesn't work. Ask others if there is any other way.

The stem comes from a question in Zhihu: "If you are suddenly laid off, what is planB", which means if you are laid off, is there any other place to go? Because planB's statement is novel, it became popular on the Internet.

In addition, the stalk corresponding to playb is "plan A", which means Plan A. If you have made multiple plans for something, you can use plana, planb, planc, etc. Name these schemes separately. Plana stands for the first plan Generally, only when plana fails will she choose other schemes.
