Well it seems completely straightforward:

tien li kou huo xien &lt;--&gt; xien xiu qi "L" t'ou
tien li kou leng xien &lt;--&gt; xien xiu qi "N" t'ou

tien tung ma t'a lan xien &lt;--&gt; xien xiu qi "N" t'ou 
tien tung ma t'a huang xien &lt;--&gt; xien xiu qi "A" t'ou 
tien tung ma t'a hei xien &lt;--&gt; xien xiu qi "B" t'ou


and of course

tien tung ma t'a qing xien &lt;--&gt; tien li kou ku chiang (qing) xien




I can't imagine why anyone would be confused by this.
