5)Did you realize that I wrote CAPITAL for high pitch and Lowercase for low pitch.
But I don’t think you MUST obey or remember all of them.
One of the reason is it’s easy to change pronunciation(high point).
ぎんこう giNKOO bank
みつびしぎんこう miTSUBISHIGInkoo
When I lived in Shanghai,I want to remember the Shanghai Dialect.
So
I wrote the pronunciation on the small paper and bring all the time.
BUT
I could not remember or even if I remember one word,but no one could hear it because the accent point was different.
Or after writing high pitch mark and low pitch mark,I can remember with confidence.
So I write high and low mark for your guideline.
