Here's something that you need to consider (or be aware of) before going to India. I've just been back from New Delhi and Agra and this is exactly what I prepared and packed for the trip. I hope this will help you.
以下是出發去印度之前的一些準備和打包事項。我剛從印度New Delhi 新德里和Agra 阿格拉回來，這也是我為了這次旅程準備的一些東西，現在就跟大家分享一下，希望會幫到大家喔。
Visa application 簽證申請
Applying for an India tourist visa is tricky. Check if you are eligible to apply for an e-visa or not. If not, you will have to apply for one in person. You will need your travel details ready when you start your application. Basically, just do it a month or two in advance so that you get your visa in time.
Currency exchange/ cash 現金換匯
Indian Rupee is a closed currency so you might not be able to find it elsewhere expect in India. So make sure you take enough cash with you so that you could exchange some money when you arrive.
International bank card 國際銀行卡
It's always a good idea to have your bank card ready. Do remember to tell your bank that you will be aboard soon otherwise they might block your card for some reasons. When you see an international bank, try to withdraw some money first as not all of the ATM machine works with international bank card.
Make sure if your vaccination is up-to-date. Hepatitis A and Typhoid are usually recommended for travellers going to India. The thing is, these vaccination do not 100% keep bacteria away and good personal hygiene is a definite.
Travel insurance 旅遊保險
This is not particularly for India but something that you should consider purchasing. There's a lot of insurance company out there; I am sure you will be able to find one that fulfil and cover your needs!
Travel essentials 旅行必需
Pack all your travel essentials like your passport, an universal adaptor and charger for your phone and camera. Keep your phone and camera with you so that you won't miss any moments.
Medicine kit 藥品包
To keep bacteria away, take some alcohol hand gel or wipe with you. Always clean your hands before eating. You will always need to take lots of tissue with you because most of the public toilets in India do not provide toilet paper rolls. Take some plasters with you just in case. Last but not least, don't forget to take a mask as the pollution is extremely serious in India, especially in New Delhi.
Summer specials 夏日特備
If you are going to India in summertime, mosquitos and bugs could be a big issue. Take an anti-bugs and mosquitos spray with you at all time to keep you away from the some disease. Sunscreen, umbrella and sunglasses are also very important too. You might also find a fan essential as well.
