點用much more?

通常用much better

eg. I got sick last week but I feel much better now.

--> more convenient --> much more convenient

effecient --> more efficient --> much more efficient

good --> better (唔會more better) --> much better !!

又例如: many --> more --> much moreconvenient

usually, much is for uncountable nouns while more is for countable nouns

in your case, it is about comparatives and superlatives
that is, big > bigger >>biggest

in exceptional cases, we do not add -er or -est
like, good, better, best
and convenient, more convenient, and most convenient

the first one change forms, while the 2nd one add more to the comparative and most to superlative

when you add much in front of a compartive, you emphasize the meaning of A LOT
for BETTER, it includes the meaning of more in it already, therefore there is no need to add another more in front

hope that helps~

much more = "再"多d 既意思.
more本身已經有"加強"一個形容詞既作用, 而加埋much響前面, 就係用黎加強個more既意思. 即係"比more更強調".

因為more + adj已經係一個比較式, 要響佢之前再強調, 就要用much. 而better本身已經係一個比較式, 所以同more一樣, 之前要更強調的話, 就要用much, 而唔使加more.
