Abstract: Embodiments of the present application provide a method and system for private communication. During operation, the system may determine a privacy level from a plurality of privacy levels associated with a private chat function of a communication application. The private chat function may be configured to transmit and receive private chat messages, and each privacy level is associated with visual effects which are different from the visual effects of other privacy levels. The system may obtain mode configuration information corresponding to the selected privacy level. The system may then configure the private chat function for the communication application based on the obtained mode configuration information, and display the visual effects for the communication application according to the selected privacy level.

Abstract: A method including acquiring a received reminder message; identifying a pin-to-top reminder message or a common reminder message from the reminder message according to a display mode configured for the reminder message; and displaying the pin-to-top reminder message in a first display area in a reminder message display page, and displaying the common reminder message in a second display area in the reminder message display page, wherein the first display area and the second display area are respectively located at different positions in the reminder message display page. With the technical solution of the present disclosure, reminder messages may be mode-differentiated and partially displayed in a pin-to-top manner, thus preventing an important message from being obscured due to too many reminder messages, helping improve the reminding effect, and improving the communication efficiency.

Abstract: A cigarette with a reduced smoke temperature and an improved flavor includes a tobacco section (1), a filter section, and a smoke backflow section arranged between the tobacco section (1) and the filter section. An inlet hole (3) is provided at the smoke backflow section near the tobacco section (1) and intercommunication with the tobacco section (1). An outlet hole (6) is provided at the smoke backflow section near the filter section and intercommunicated with the filter section. Multiple airflow baffles (5) are staggered up and down inside the smoke backflow section and form a smoke backflow channel (4) which is sinuous. A first end of the smoke backflow channel (4) is intercommunicated with the inlet hole (3), and a second end of the smoke backflow channel (4) is intercommunicated with the outlet hole (6). Smoke enters the smoke backflow section from the inlet hole (3), and then passes through the smoke backflow channel (4).

Abstract: Embodiments of the present application provide a method and system for communication. During operation, the system may receive a message sent by a sender to multiple recipients. The system may determine that a reply mode of the message is set to a private mode which restricts permission to receive replies to the message. The system may receive a reply message sent by a recipient in response to the message. The system may identify, among the sender and the multiple recipients, a communication party with permission to receive the reply message. The system may then send the reply message to the identified communication party.
