Regarding the safety of studying abroad, recently, there was a case that attracted much attention. I graduated from Sun Yat-sen University with a bachelor's degree and graduated from YINGYING ZHANG, Peking University with a master's degree. In April this year, I went to the University of Illinois at Urbana-Champaign for exchange and study, and lost contact on June 9. This incident has aroused widespread concern of local Chinese and the people of the motherland. On June 30th, the FBI announced the arrest of a 27-year-old man suspected of kidnapping YINGYING ZHANG, a visiting scholar in China. Regrettably, the FBI expressed its belief that YINGYING ZHANG was dead. This also sounded the alarm for the safety of studying abroad. The following is the iron law of studying abroad: Iron Law 1: Keep a low profile and don't "show off your wealth" to give the bad guys a reason not to hurt you. Children in China lack safety awareness, and most of the time they are "asking for trouble". In recent years, the incidents of robbery of China students exposed by the media are all related to "showing off their wealth", and even some children were robbed just after they bought a "luxury car". There is an old saying in China: If you are not afraid of thieves stealing, you are afraid of thieves thinking. This kind of answer is actually to dispel the bad guys' attempts and let them have no reason to hurt themselves. Iron Law 2: Girls should learn to distinguish "bad guys" skillfully when they are in the same trade, especially women. "Walking with peers" and "not being alone with strange opposite sex" are almost the "iron laws" given by experts for the safety of studying abroad. Having a companion not only helps to avoid being invaded by the bad guys, but also helps in time even when there is a dangerous event. Iron Law 3: Don't be too confident. Be familiar with the life-saving information around you. One incident was caused by an international student from China taking part in a safety simulation exercise in a foreign school. When the alarm sounded, all the students in the school left the classroom, except the international student from China. In the eyes of this foreign student, these drills are just a form, not a real disaster. Later, the school gave the student a severe punishment, "because the school thought his behavior was a potential safety hazard and would probably harm people in the future." It is precisely because we have not received good safety education in primary and secondary schools that many foreign students turn a blind eye to these life-saving information around them when danger really comes.
