  In this paper, with a set of high-resolution He I 10830 \AA\ filtergrams, we
select an area in a plage, very likely an EUV moss area, as an interface layer
to follow the clues of coronal heating channels down to the photosphere. The
filtergrams are obtained from the 1-meter aperture New Vacuum Solar Telescope
(NVST). We make a distinction between the darker and the brighter regions in
the selected area and name the two regions enhanced absorption patches (EAPs)
and low absorption patches (LAPs). With well-aligned, nearly simultaneous data
from multiple channels of the AIA and the continuum of the HMI on board SDO, we
compare the EUV/UV emissions, emission measure, mean temperature, and continuum
intensity in the two kinds of regions. The following progress is made: 1) The
mean EUV emissions over EAPs are mostly stronger than the corresponding
emissions over LAPs except for the emission at 335 \AA. The UV emissions at
1600 and 1700 \AA\ fail to capture the difference between the two regions. 2)
In the logarithmic temperature range of 5.6-6.2, EAPs have higher EUV emission
measure than LAPs, but they have lower mean coronal temperature. 3) The mean
continuum intensity over EAPs is lower. Based on the above progress, we suggest
that the energy for coronal heating in the moss region can be traced down to
some areas in intergranular lanes with enhanced density of both cool and hot
material. The lower temperature over the EAPs is due to the greater fraction of
cool material over there.
