台北からツーリングでやってきた，というバイク集団も工事待ち。後に関子嶺温泉で出会うことになる。ようやく通過した工事箇所は崖が極めて厳しい。台湾の東岸でも同じように補修している場所があったが，なるほどこの地形で道の維持もそう簡単ではないと実感する。＠21号線，阿里山へ The bike touring group from Taipei also waited for road repair...We will meet later at Kanigori Onsen...Cliffs were extremely severe at the road-collapse point passed through. There were also some places which were repaired, same as here, also on the east coast of Taiwan. Indeed Realized that maintaining the road in this terrain is not so easy. ＠Route21, to Alishan
