*Kev nyab xeeb (txais yuav huab tswj hwm lub platform kom ntseeg tau kev nyab xeeb ntawm cov neeg siv khoom)
*Kev ntseeg tau ntawm is taws nem (siv lub internet tshwj xeeb kom ntseeg tau tias ua haujlwm ruaj khov thiab ruaj khov.
*Rov siv internet xov tooj ntawm tes tam sim no (nrawm thiab pheej yig).
*Tus nqi thoob ntiaj teb thiab kev ncig.
*Kev hloov pauv hluav taws xob tsis zoo: ΔV≤ ± 1 teeb liab sib npaug.
