The fundamental group of \(X\) at \(x_0\) is \[\pi_1(X, x_0) \;:=\; \bigl\{[\gamma] \mid \gamma \text{ is a loop based at } x_0\bigr\}\] equipped with the group operation of concatenation: \[[\gamma] \cdot [\delta] := [\gamma * \delta], \qquad (\gamma * \delta)(s) := \begin{cases} \gamma(2s) & s \in [0,\tfrac{1}{2}] \\ \delta(2s-1) & s \in [\tfrac{1}{2},1] \end{cases}\] The identity element is the class of the constant loop \([c_{x_0}]\), and the inverse of \([\gamma]\) is \([\bar\gamma]\) where \(\bar\gamma(s) := \gamma(1-s)\).
围炉，是闽南地区对年夜饭的叫法。除夕夜，全家老小围坐桌前，除了蒸鱼、炒面、炸物外，桌上必有一道以骨汤吊底的清汤火锅，烫海鲜、丸子、青菜吃，不蘸任何料碟，这是没被油碟、麻酱、火锅底料入侵过的古早味。
