These two brands are first-line brands; However, Liansu is the only listed company in the pipeline industry and the first group company in China to produce water pipes. Its comprehensive strength should belong to NO 1, and its cost performance is also the highest. The only regret is that it spends less on advertising! Rifeng is a rising star with good quality and loud advertisements, but low cost performance. The worst thing is that there are too many hydraulic commissions. After all, Rifeng's marketing slogan is to regard the hydraulic industry as God! I have been engaged in the pipeline industry for 20 years! )
