money lui1

 I so happened to browse Zhang Xiao Shan's dictionary and on page 762 [second edition], I saw what he has to say about lui1. I therefore made notes so I could share with you. He did not indicate that lui1 is a foreign word or else those Teochew historical dramas would not have used the word lui1. 

As I have written before, I do not believe lui1 has anything to do with duit which is money in Malay 聲音差遠 ! I wrote in Mandarin that the sounds are very different [i.e. between lui1 and duit]

lui1鐳｜镭	ancient Chinese copper coins	tong2qian2 銅錢｜铜钱
lui1鐳｜镭	coin	ying4bi4 硬幣｜硬币
hao5 毫 has the same meaning as gag4 角 and in Mandarin is mao2 毛 which is one tenth ⅒ of a dollar or Yuan
