Comments

Mandarin Chinese has four tones. The first tone is a flat, high tone. The second tone is a rising tone. The third tone first falls a little and then rises. The fourth tone is a falling tone.

Examples

			a(21) = 421 because the characters in the Chinese word for 21, "er shi yi", are pronounced with the fourth, second and first tone, respectively.

Comment from Michio Ozeki, Aug 01 2016, in an email to N. J. A. Sloane, Jul 01 2016 (There was a mistake in A274177, but it is better to place the explanation here.) (Start):
The number 121 is pronounced hya-ku-ni-juu-i-chi, not hi-ya-ku-ni-ju-i-chi.
Hya is similar to ca in "can" or ca in "cat". It is a kind of a complex vowel.
There is a clear distinction between ju and juu.
The pronunciation of ju is quite similar to ge in the French name Lagrange.
The pronunciation of juu is similar to ew in "few" or jewel.
I give you another instance of the pronunciation of "hundred".
381 is pronounced sa-n-bya-ku-ha-chi-juu-i-chi.
877 is pronounced ha-ppya-ku-na-na-juu-na-na.
So there are 6 mora in 121, not 7. (End)

Examples

			4 can be 'yon' or 'shi'. 'yon' has 2 mora, while 'shi' has 1, so a(4) = 1.

			VII in Braille (with the "Roman num" character):
  o  o      o    o
     o    o    o
  o  o o
Therefore a(7) = 10 - 2 = 8.
