As far as I know, many students in Tsinghua University use bicycles as a means of transportation on campus. Just like other places, whether it is a university campus or a city street, car or bicycle theft is a risk. Although Tsinghua University has taken some measures to improve campus security, such as installing surveillance cameras, strengthening police patrols and providing bicycle parking areas, due to the size of the campus and the density of people, the possibility of bicycle theft cannot be completely eliminated.

In order to minimize the risk of bicycle theft, I suggest you take the following measures:

1. Use high-quality locks, such as U-locks or chain locks, and lock them correctly on the bicycle frame and fixed objects.

Try to park your bike in a crowded place, so that thieves will be more uneasy.

3. Try to park your bike in the area covered by the surveillance camera.

Don't put valuables in the basket or in the basket.

It is best to buy an unattractive bicycle to reduce the possibility of attracting the attention of thieves.

Despite these measures, there is no guarantee of absolute safety, so please use and keep your bike carefully. If it is unfortunately stolen, please call the police and ask for help in time.
