Tuam Tshoj Yuav Tswj Kev Xa Khoom Tawm Ntawm Cov Khoom Siv Superhard Pib Thaum Lub Kaum Ib Hlis 8, 2025

Tuam Tshoj Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam thiab Lub Chaw Haujlwm Saib Xyuas Kev Lis Kev Cai tau tshaj tawm tsab ntawv tshaj tawm No. 55 ntawm xyoo 2025, lees paub cov kev ntsuas tswj kev xa khoom tshiab rau cov ntaub ntawv superhard tshwj xeeb. Txoj cai lij choj yuav siv rau Kaum Ib Hlis 8, 2025, thiab lub hom phiaj yog los tiv thaiv kev ruaj ntseg hauv tebchaws thiab ua tiav cov luag haujlwm thoob ntiaj teb tsis txhob nthuav dav riam phom.

Cov Khoom Tseem Ceeb Hauv Kev Tswj Xyuas Kev Xa Khoom Mus Rau Lwm Lub Tebchaws
