Who is your son? you idiot!
Actually we were Chinese for 1,000 years, not your slaves, you illiterate.
Yes, that´s true Vietnam is still a developing country. Yes, it is still poor and backward thanks to devasting wars including against China. Don´t forget, before these sadly events starting with France invasion, Vietnam was rich and mighty, a regional power with vassals including Luang Prabang, Vientane, Burma, Tran Ninh Plateau in eastern Laos, and two countries called "Water Haven" and "Fire Haven", which were actually Malayo-Polynesian Jarai tribes living between Vietnam and Thailand.
Who talks big? Who shows arrogance against smaller nations and bows to the mighty?
Remember, it was China arrogance that brougth you 100 years of humiliations. Learn history, you fool!
