i was born under the rat sign.what is my lucky number and lucky year.....and about lovepartner.

Your lucky numbers are 2 and 3.
Generally, no a certain year can be considered the lucky year. In my opinion, once you work hard and seek for your garget, every year can be thr lucky year.
According to the Chinese atrology, people with the zodiac signs of dragon, monkey and ox can be your lovely partner, just for referrence.
