This one calls –
“Kuei hua kang lao
T’ien pao t’sui
Tzu erh po po.”
This peddler carries a round wooden box “yuan lung” on his arm. This box has four sections and in it he carries three kinds of articles for sale:
(1) The “kang lao” is a kind of flat round cake made from flour and sugar flavored with cinnamon (“kuei hua”).
(2) The “pao t’sui” is a very thin dry cracker about the size of a griddle cake but almost as thin as paper. It is made of flour and water and flavored with sesame seed.
(3) The “tzu erh po po” is a small cake made of flour, water and sugar. A wooden mould is used to cut the batter into small flower shaped cakes which are cooked until very hard – like pebbles – hence the name “tzu erh”. These are made very hard so as to keep the younger generation busy eating one candy for a long time – like an “all day sucker”.
