We study the non-Ohmic current-voltage characteristics
for the tunneling into fractional quantum Hall liquids
in terms of chiral Tomonaga-Luttinger liquid (TLL) theory.
Generalizing a model proposed by Lee and Wen, we
investigate the effects of interaction between the charge
and neutral modes.
For small 
we found that
the chiral TLL model could successfully explain the
observed approximate 
dependence (
).
