What are the essential things for a week trip to Singapore, Malaysia and Thailand, and what are the essential things for people who don’t have much money only to find out when they get there?

The essential items for traveling to Singapore, Malaysia and Thailand are summer equipment, toiletries, slippers, hats, umbrellas, swimsuits, and clothes that are breathable and easy to clean. Note: You must bring high-power sunscreen. The highest domestic sunscreen is generally 3++. It is recommended to buy one in the duty-free shop at the airport. Recommendation: L'Oreal's 5++ sunscreen, the effect is good. It’s not the tan that’s the problem, it’s the sunburn, especially if you spend a lot of time at the beach. Southeast Asia pays attention to environmental protection, so hotels do not provide toiletries. As for clothing, you should bring a pair of trousers. Some temples do not allow shorts, but now there are kind-hearted aunts in the temples who prepare blankets, and you can also make Arab boys and girls. Bring long sleeves because the air conditioning on tour buses is really low. Don’t ignore it. It’s better to learn more about it. You can ask a travel agency.
