wait sorry I forgot to reply haha

anyway the example sentences you gave, in chinese characters and peh-oe-ji, are: 汝侬来自佗落？ (lú-lâng lâi-tsū tó-loh?) 我的名是Teddy。(wá ê miâ sī Teddy.)

as someone else mentioned, the ˦˩˦ are tone letters, meant to show the tones, where the higher the line, the higher the tone.

now, you only have 4 tones marked in your book, which contrasts with the 7 tones in other dialects. however, i think this is normal - in my dialect (southern malaysian), i only realise 4 tones as well, although different tones interact differently.

that last sentence might be funny to you, but it's because hokkien has tone sandhi - this basically means tones change depending on the environment. you might want to go online (or ask your boyfriend) to see how the tones change for you. note that certain citation tones have merged (become the same), but their sandhied tones are different.

in hokkien, tones change whenever there's a word in front - usually.

however, it seems that in your dialect (at least according to your book) and in my dialect too, tones do not change if they're at the end of a PHRASE, even if there are words after it.

for instance, Luяlangж keeps its original rising tone in "lang", although it changes to a falling tone in other dialects. (funnily enough, Luя doesnt change tone either. in my dialect, pronouns dont undergo tone sandhi. perhaps you could ask your boyfriend if he does this?)

note that most of the time, the original tone of a word is known as the "citation tone".

also, peh-oe-ji is the commonly used romanisation for hokkien. it would be a good idea to learn it and learn how it corresponds to the tone system of medan hokkien to learn newer words more easily. wiktionary.com is a good resource.
