Chao cac ban trong dien dan,
Minh dang lam mach do nhiet do nhưng khi mo phong thi nó nhay, ko hieu sao nua code ktra di ktra lai nhung chua tim duoc cho sai, cac ban trong dien dan ai da lam ve mach do nhiet do chi giup voi, cam on cac ban rat nhieu, mình gui file mophong va code len cac ban giup mình voi nhe.
