Can Durians Flower at Early Age?

My notion was very skeptical. I believed that durians will only flower after 4 or 5 years after planting in the field. Some people showed in the WA that durians fruit at early age. I told that it was faked .I was wronged.However, it is true.

 I met the guy who show the pics about early flowering in durians in Indonesia.He told me what secrets he had.
