Qeexitaan Sare oo Sare Shiinaha oo kuyaala Shiinaha oo dhoofsaday
Si kasta oo loo isticmaalo macaamiisha cusub ama dukaan horeba, waxaan aaminsanahay muujinta dheer iyo xiriir aad u aamin badan oo ku saabsan qeexitaanka sare ee Shiinaha oo la raacayo H80 H90 c1100 C1100 C1100 C1620 C1620 C1620 C1620 C1620 C1100Gabal fidsan, Waxaan had iyo jeer ku dadaaleynaa inaan horumarino adeeggeenna oo aan u bixino badeecadaha tayada ugu wanaagsan ee qiimayaasha tartamaya. Wax weydiin ah ama faallo ayaa si aad ah loogu mahadnaqayaa. Fadlan si xor ah nala soo xiriir.
Si kastaba ha noqotee ma macmiil cusub ama dukaan horeba, waxaan aaminsanahay muujinta dheer oo xiriir la aaminayGabal fidsan, Shiinaha naxaas ah, Waxaan sumcad wanaagsan ku qaadanay badeecada tayada leh ee xasilloon, si fiican u soo dhoweeyey macaamiisha guriga iyo dibedda. Shirkaddeena waxaa hagi doona fikradda ah "istaaga suuragga gudaha, oo lagu dhex socdo suuqyada caalamiga ah". Waxaan si daacad ah u rajeyneynaa inaan ganacsi la yeelano macaamiisha guriga iyo dibedda labadaba. Waxaan rajeyneynaa iskaashi daacad ah iyo horumar guud!
