Studying abroad in the UK, what things are expensive there and it's best to bring back from home? Personal Documents: - Passport, visa, CAS, and various copies - Original and copies of admission notice - Graduation certificate (copies of degree and diploma and English documents) - Passport photos, both blue and white backgrounds (bring a few extras) - British pounds in change - Carry a pen and paper in your carry-on luggage Electronic Products: - Laptop - A 2-3 meter long ethernet cable, remember to test it in advance - Power adapter plug, Bull brand is recommended - Multi-function plug board - Various chargers, etc. Kitchenware: - A small rice cooker (it's best to bring a multifunctional one that can make soup, cook rice, and make porridge), it'll make our life much more convenient. - 3-4 pairs of chopsticks, so you won't run out when friends come over. There's ice water everywhere in the UK, so you can bring a thermos cup for hot water. - You can bring some seasonings you like, such as hot pot base and braised pork, but you don't need to bring other basic items like oil and salt since they're available in the UK. Clothing: - Girls must bring underwear because it's not easy to buy good ones abroad! - Bring a few favorite accessories, as we can't avoid shopping in the UK. Essential Medications: - Cold medicine, painkillers - Thermometer (be careful not to break it) - Band-Aids, for bruises and injuries - Allergy medication (useful for sensitive skin or if you're not used to the local climate) - Eye drops - Last time I watched a British blogger, they highly recommended Huoxiang Zhengqi Water!! Others: - For those with myopia, bring an extra pair of glasses - Also, contact lenses and colored lenses - And definitely bring an umbrella in the UK, after all, it's known as the rainy city! - If there's anything I missed, feel free to add it in the comments section!
