Lub ntiaj teb niaj hnub xav kom tib neeg tawm ntawm lub cev thiab nyob hauv digital.

Nrog rau qhov pom ntawm Al thiab kev nthuav dav ntawm cov neeg siv thev naus laus zis tso siab rau hauv lub tshuab ntau dhau thiab ntseeg nws ib txwm yog qhov raug.

"Tiag tiag" yog lub hom phiaj txhawm rau txhawm rau qhov kev ntseeg cuav no los ntawm kev tsim cov cuav cuav kuaj ntsuas. Tib neeg yuav yooj yim ntseeg tias tiag tiag tab tom ua haujlwm tab sis thaum muab cov lus teb tsis raug nws yuav ua rau lawv qhov muag tsis pom kev ntseeg hauv thev naus laus zis.

Kauj Ruam 1: Kauj Ruam 1: Tua Hluav Taws Xob

Vim tias kuv txoj haujlwm tsuas muaj ib lub teeb xwb, yog li nws yooj yim heev rau cov laug. Qhov teeb meem tseem ceeb yog thaum pib, Kuv tau siv ob lub teeb, tab sis kuv tsis tau npog qhov raug tam sim ntawd. Yog li thaum ob lub xov hlau txuas ua ke. Nws luv luv.
