Chikwama cha thonje ndi mtundu wa chikwama chansalu choteteza chilengedwe, ndi chophatikizika komanso chosavuta, chokhazikika, ndipo sichiipitsa chilengedwe. Imagwiritsidwanso ntchito, potero imachepetsa kuipitsidwa kwa chilengedwe kwambiri.

Matumba a thonje: Matumba ansalu otchuka padziko lonse lapansi osasamalira chilengedwe. Nsalu ya thonje imapangidwa ndi thonje lachilengedwe, ndipo matumba ambiri a thonje okonda zachilengedwe sadayidwa kawirikawiri.

Matumba a thonje ndi ochezeka ndi chilengedwe ponena za zipangizo. Komanso, chifukwa mtengo wamatumba a thonje ndi wapamwamba kusiyana ndi nsalu zopanda nsalu, makampani ndi mayunitsi omwe amawasankha nthawi zambiri amakhala okonda zachilengedwe komanso amakhala ndi mphamvu zambiri. Ndiwonyozeka ndipo alibe kuipitsa chilengedwe; kulimba kwake kumakhalanso kwakukulu kwambiri kuposa nsalu zopanda nsalu, ndipo mizere yake yabwino imakhala ndi zotsatira zabwino zosindikizira, zomwe zimakhala zamphamvu kuposa nsalu zopanda nsalu; nsalu yake ndi yofewa komanso yosavuta kupindika Pita; chifukwa ndi thonje, ndizosavuta kuyeretsa ndi nsalu zopanda nsalu. Chikwama ichi ndi choyenera kwambiri ngati thumba logulira komanso chokhazikika. Makampani ambiri amasindikiza logo ya kampaniyo pansalu ya thonje, yomwe imakhala ndi zotsatira zabwino zolengeza.
