號

I like to talk about this character 號 today.

Most of us should know ho7bhê2 號碼 as in "number" and said in Mandarin as hao4ma3.

However, the Mandarin er4hao4 二號 - the second day of the month is said and written as ciu1dzi7 初二 in our language.

but ho7 號 means to reserve or to take up or occupy: 
for example
soiⁿ1 ke3 ho7 gai5 iu7 先去號個位。｜First, go and reserve a seat.

hao6 號 - in our language means nickname and in Mandarin as wai4hao4 外號

Then there is hao1 號 which means to cry.  For example, 

hao1tiⁿ1gio3dzig8 號天叫日 means to cry bitterly: calling on heaven and the sun 

so, if we do not have PêngIm, how would we know how to say or read 號
