I'm a East Asian preparing to celebrate the Lunar New Year and have found this piece of decoration. The Chinese character on it is, I'm pretty sure, a Traditional one, literally full of strokes and pretty calligraphic. I've tried looking up this character in our most reliable Han dictionary (from Traditional Chinese characters to our language), but failed (partly because it's a Han dictionary). Particularly, I've researched (groups of) radicals of 辵 (辶) and 宀 in the dictionary (and failed, as mentioned).
Now I'm here to seek help. What is this character?
