As Liu explained, the user viscosity in lower-tier cities is higher than that in first and second-tier cities.

正如刘所解释的，低线城市的用户粘性高于一二线城市。

The smaller number of stores in lower-tier cities means higher repeated purchases at one store and higher user viscosity.

低线城市的门店数量越少，意味着一家门店的重复购买量越高，用户粘性越高。

While online retailing value increased 9 percent year-on-year to reach 6.08 trillion yuan during the first seven months of the year, as found by the Ministry of Commerce, a physical presence is crucial to enhance the brand's recognition and user viscosity, Yang said.

Experts from Industrial Securities believed that personal pensions will start the one-stop transformation at securities firms combining wealth management and investment advisory services, with user viscosity largely enhanced.
