Using the new equipment of the Shanghai Tian Ma Radio Telescope, we havesearched for carbon-chain molecules (CCMs) towards five outflow sources and sixLupus I starless dust cores, including one region known to be characterized bywarm carbon-chain chemistry (WCCC), Lupus I-1 (IRAS 15398-3359), and one TMC-1like cloud, Lupus I-6 (Lupus-1A). Lines of HC3N J=2-1, HC5N J=6-5, HC7NJ=14-13, 15-14, 16-15 and C3S J=3-2 were detected in all the targets except inthe outflow source L1660 and the starless dust core Lupus I-3/4. The columndensities of nitrogen-bearing species range from 10$^{12}$ to 10$^{14}$cm$^{-2}$ and those of C$_3$S are about 10$^{12}$ cm$^{-2}$. Two outflowsources, I20582+7724 and L1221, could be identified as newcarbon-chain--producing regions. Four of the Lupus I dust cores are newlyidentified as early quiescent and dark carbon-chain--producing regions similarto Lup I-6, which together with the WCCC source, Lup I-1, indicate thatcarbon-chain-producing regions are popular in Lupus I which can be regard as aTaurus like molecular cloud complex in our Galaxy. The column densities of C3Sare larger than those of HC7N in the three outflow sources I20582, L1221 andL1251A. Shocked carbon-chain chemistry (SCCC) is proposed to explain theabnormal high abundances of C3S compared with those of nitrogen-bearing CCMs.Gas-grain chemical models support the idea that shocks can fuel the environmentof those sources with enough $S^+$ thus driving the generation of S-bearingCCMs.
