A text in English: If a rider is thrown from a horse but has a foot caught in the stirrup, they could be dragged if the horse runs away. To minimize this risk, a number of safety precautions can be taken.
The same text in Chinese (Simplified):
如果骑手从马上被甩下来，但有一只脚卡在马镫上，那么马在奔跑时可能会拖着他走。为了将这种风险降至最低，可以采取一些预防措施。
