Father is going to travel to Thailand and wants to learn some English conversations. He has no foundation in English. Can you recommend a book for him to study? thank you

No, it's just a few days' trip. Don't be so heavy.

Take an arbitrary smart phone and install an arbitrary Chinese translation software. Your father can't even type on his mobile phone, can he?

By the way, actually you don't need so much English to go to Thailand. Your father is always guided by a tour guide.

Even if your father travels by himself, it is necessary to distinguish between the men's room and the women's room. M and w can be distinguished.

All that remains is one sentence: how much is it? No matter what others say, say no, and then take out your mobile phone and let them press the number.
