Nthawi zonse pali zidutswa zachikale zomwe timapeza m'moyo wathu zomwe zimatipangitsa kumwetulira nthawi zonse tikamaganiza za iwo.Monga nsapato zazikopa zoyera zowoneka bwino mu kabati yanu ya nsapato.
Komabe, zimakukwiyitsani nthawi zina kukumbukira kuti pakapita nthawi, nsapato zomwe mumakonda sizikhala zoyera komanso zonyezimira, ndipo pang'onopang'ono zimakalamba komanso zachikasu.
Tsopano tiyeni tipeze chomwe chikuchititsa kuti chikopa choyera chikhale chikasu——Mu 1911 AD Dr. Stiasny adapanga buku lopangidwa ndi tannin lomwe lingalowe m'malo mwa masamba.Poyerekeza ndi masamba a tannin, tannin yopangidwa ndi yosavuta kupanga, imakhala ndi katundu wotentha kwambiri, wopepuka komanso wolowera bwino.Motero yafika pa udindo wofunika kwambiri pantchito yofufuta zikopa pazaka zana zachitukuko.Muukadaulo wamakono wofufuta, mtundu uwu wa tannin wopangidwa umagwiritsidwa ntchito pafupifupi m'nkhani zonse.
Chifukwa cha mapangidwe ake osiyana ndi ntchito, iwo nthawi zambiri amatchedwa kupanga tannin, phenolic tannin, sulfonic tannin, disperse tannin, etc. commonality tannins awa ndi monomer awo nthawi zambiri wa phenolic mankhwala dongosolo.
