What should I bring if the weather is fine in Vietnam in March?

1, mobile phone Before I go to Vietnam by myself, the information on the Internet will generally tell you: "According to the relevant regulations, visitors to Vietnam are not allowed to bring cameras, cameras with focus, computers, VCDs, mobile phones and other items." If you bring something that can't cross the border, the tour guide will generally suggest that you deposit it at Dongxing Hotel. Of course, the storage fee is not low-a mobile phone costs about 20-30 yuan. Because we didn't want to cause any more trouble, and considering that there might be no cell phone signal in Vietnam, LG and I left our cell phones with our friends in Nanning. However, in fact, it is necessary to bring a mobile phone to Vietnam, and it is easy to carry it through customs. China communication signals are generally found in cities along the Vietnamese border, especially Dongxing. Carrying a mobile phone with you will increase people's psychological security. Accommodation in Vietnam is generally in private hotels, and the wake-up service is very poor. It is also necessary to bring your own mobile phone as an alarm clock. If you take your mobile phone to the border, you'd better not deposit it, because it's very troublesome to go back and get it back. As long as you turn off your phone and hide it in your pocket, you can usually get away with it-several people in our group have passed the customs smoothly. There is also a limit on the amount of cash you can carry with you. But if you carry a lot, put it in several pockets on your body, not in your luggage, so as not to be detected by the X-ray machine. I didn't want to buy souvenirs in Vietnam, so I only brought a small amount of RMB cash. Later, I found that not bringing American dollars was the biggest mistake. I have traveled to Thailand and South Korea before, and I know the benefits of the US dollar, but I didn't expect the Vietnamese people to welcome the US dollar far more than the RMB (previous online information misled me that the RMB is a hard currency in Vietnam and can be used everywhere). In Hanoi and Haiphong, people rarely hold RMB. When you use it, they either don't want to accept it, or give you a very low exchange rate and give you a bunch of Vietnamese dong. So comrades must remember that "traveling abroad brings us dollars." At that time, my brain was a little short-circuited and I forgot this truth. I didn't buy anything satisfactory in Vietnam, but spent RMB at a net low exchange rate. I was wronged to death. You can also go to /gl/ to see the precautions for traveling in Vietnam.
