There are several discoloration levels below 255, and I can't remember the specific ones. The first color change takes about 100.
It is suggested to settle accounts every afternoon 1. 1, your recommendation will be reduced by 3. The 0 recommendation will remain unchanged.
According to the truth, within 24 hours, everyone can only recommend the same person 1 time, but if you log in after a short time, you can repeat the recommendation. So I often see people in the city going up and down, which is a recommendation.
Every number, as long as it passes 2 turns, will be recommended 9 times a day. If it passes 1 minute, no matter how much is left, it will change back to 9 times.
The most convenient way is to recommend double numbers by yourself, 9 every day, and occasionally take them from others, and they will be full within one month. If you drive three times, it will be faster if you drive four times.
After the recommendation of 255, there will still be three 1 points less every day, so we should continue to push it every day.
