People hang up decorations, especially pairs of Chinese poems (couplets) on either side of their doors. Some put pictures of Taoist gods on the doors to scare away bad things. Live plants suggest growth, and flowers suggest coming fruits. Pussy willow is common in some places because its Chinese name sounds like "money coming in". It is very common for big decorations to look like the animal for the new year, so that 2017 had Rooster and Chicken pictures and statues and 2018 will have Dogs.
