In Hong Kong herbal tea shops, you will see a tea called "廿四味" (24 flavours)
(you will also hear "廿蚊" to mean "20 dollars" in small shops)
In this case 廿 (niàn or pán) has the meaning "20".
Are there any other chinese numerals that represent unusual numbers?

I guess 99% native speakers have no idea about it. – halfelf Oct 29 '12 at 10:00niàn. Since my mother is from Shanghai, I know a little Shanghainese. – halfelf Nov 01 '12 at 06:07
