SA387 Gr5 vs Gr9: Yuav Ua Li Cas Xaiv
XaivTIAB SA 387 Gr5yog:
Kev khiav hauj lwm kub yog nruab nrab
Nyiaj txiag yog qhov tseem ceeb ntawm kev xav
Kev pabcuam ib puag ncig tsis tshua muaj siab
XaivTIAB SA 387 Gr9yog:
Kev khiav hauj lwm kub yog siab
Ntev - lub sij hawm creep kuj yuav tsum tau
Cov khoom siv raug rau hydrogen lossis oxidizing ib puag ncig
