Once you are signed up, you can only move upward through a process called ‘Upgrade‘.
Usually, Longrich will open a window of upgrade to enable you move from your current entry level to another.
Once this window is opened, you can upgrade from one level to any level. For example, if you are currently sitting as Silver, when the Upgrade window opens, you can upgrade to Gold, Platinum or VIP.
You upgrade by buying products worth the difference of PV (Product Value) between your current level and your desired entry level.
For example, if your current level is Silver with 120 PV and you desire to upgrade to Platinum which has 720 PV, you need to fill form to buy products worth 720-120 = 600 PV. Remember to indicate ‘Upgrade’ on the Form.
