The word "宴会厅" is formed by sequentially combining three characters: 宴, meaning "banquet" or "feast"; 会, meaning "gathering" or "meeting"; and 厅, meaning "hall" or "room". The first two characters together, 宴会, constitute the concept of a "banquet", and adding 厅 specifies the venue, resulting in a compound term that literally denotes a "banquet hall".
