spelling out whole numbers in Hanyu Pinyin

By request, here’s the pattern.

Pay particular attention to the cases of wàn (? / ?) and yì (? / ?). When the numbers quantifying those are greater than ten, wàn and yì are written separately.

8 b?
58 w?shíb?
658 liùb?i w?shíb?
5,658 w?qi?n liùb?i w?shíb?
35,658 s?nwàn w?qi?n liùb?i w?shíb?
435,658 sìshís?n wàn w?qi?n liùb?i w?shíb?
9,435,658 ji?b?i sìshís?n wàn w?qi?n liùb?i w?shíb?
79,435,658 q?qi?n ji?b?i sìshís?n wàn w?qi?n liùb?i w?shíb?
379,435,658 s?n q?qi?n ji?b?i sìshís?n wàn w?qi?n liùb?i w?shíb?
6,379,435,658 liùshís?n yì q?qi?n ji?b?i sìshís?n wàn w?qi?n liùb?i w?shíb?

Still higher units follow the pattern of wàn and yì.

Note: When líng (zero) is a medial, it is always written separately.

507 w?b?i líng q? ????
40,507 sìwàn líng w?b?i líng q? ???????

  1. Very helpful.
    Just to be sure, is the following correct (regarding the separation of “wa?n”)?

    1010000 – y?ba?i líng y? wa?n
    1100000 – y?ba?i y?shí wa?n
    100010000 – y?yì líng y? wa?n
    100100000 – y?yì líng y?shí wa?n

    Thanks.
