Thaum tag lawm, txhua yam koj yuav tsum ua yog ntsaws nws mus rau hauv USB chaw nres nkoj thiab saib nws lub teeb tawm. Yog li koj mus, nws yog ua tiav. Koj tuaj yeem txuas nws mus rau qhov txuas txuas txuas thiab nws yuav ua haujlwm zoo li cov kab mob cab Ib qho ntxiv, koj tuaj yeem ntsaws nws rau hauv lub USB them nyiaj nqa tau; uas muaj ntau cov lus qhia, thiab siv nws zoo li lub teeb me me. Tab sis yog tias nws tsis ua haujlwm, tshem nws tam sim vim tias tej zaum yuav muaj hluav taws xob luv uas yuav ua rau koj puas USB chaw nres nkoj, tsis yog lub cuab yeej.
