As an AI language model, I do not have access to real-time information or data. However, I can provide some general information about Vietnam's northern region where Hanoi is located.
The northern region of Vietnam, including Hanoi, experiences four distinct seasons: spring, summer, autumn, and winter. The temperature can vary greatly depending on the season, with the coldest months being December and January and the hottest months being June and July.
In terms of weather patterns, the northern region of Vietnam is affected by the monsoon season, which brings heavy rainfall from May to September. The region is also prone to typhoons and tropical storms during this time.
As for the lottery or xổ số in Vietnam, it is a popular form of gambling in the country. The results of the lottery are announced daily, and there are several different types of games with varying odds and payouts. However, gambling is illegal in Vietnam for locals, and only foreigners with a valid passport are allowed to enter casinos.
