-$$\begin{gathered} In the character of Vietnamese people, there are various weaknesses \\ and strengths that are both our advantages and obstacles to the new \\ requirements of the times. One of the strengths of Vietnamese people \\ that is recognized by the world is intelligence, intelligence and sensitivity \\ to new things. Ly Quang Dieu, the eminent Singaporean leader, praised \\ the Vietnamese people: "Vietnam is the second Jewish tribe of Asia". \\ Such strength is extremely impor\tan t and very useful for us in the \\ society of tomorrow, helping us to grasp the modern scientific and \\ techno\log ical achievements of the world and apply them to conditions, \\ specific circums\tan ces of the country. But that strong point often goes \\ hand in hand with another weakness that is haste, haste and \\ superficiality. The intelligence of our Vietnamese people is \\ incomplete and has never been properly encouraged. The \\ Vietnamese people\text{'}s intelligence is just temporary intelligence. It is \\ called cleverness. Good at improvisation but not in science. Those \\ characteristics - including weaknesses, belong to the Vietnamese \\ people. We cannot deny or deny weaknesses. To meet the \\ requirements of the new era, Vietnamese people need to admit \\ it frankly and quickly "fill in the gaps". \end{gathered}$$
