An unexpected pleasure though was the sight of mangrove swamps in the national park, which reminded me of those fast disappearing mangroves at Tamsui outside Taipei, only saved from total demise by environmentally alert citizens.
倒是在公園，意外看到了一大片的「水筆仔」﹘﹘紅樹林。這種樹，在淡水一帶，原本很多，差一點絕種，還好有姜保真大聲疾呼才開始獲得保護。所以一見了這樹，我就叫它「保真的樹」。不過，淡水人都叫它「水筆仔」的。
