If the stick comes within 25 cm of a wall or other things, it will sound the alarm to (警告)the user. The stick's BDS system also allows users to be found if they get lost.
His teacher Mr. Zhang noticed his talent and （建议）that he should take part in inventing competition, which was organized by (当地的)government. After trying for many times, he finally made it and won the first place in the competition. Now the walking sticks are (广泛地) used by the old and the disabled. Many accidents are (避免) with the help of the walking sticks.
Zikuan's parents took (骄傲)in what he had done. In order to develop Zikuan's creativity, his parents always (鼓励) him to think more ideas that pandas are well worth considering and take him to different invention fairs.
