The Treaty of Mutual Assistance between France and the Soviet Union is a treaty concluded by France and the Soviet Union to defend against German fascist aggression. Signed in Paris on May 2, 1935, effective on March 27 of the following year, valid for 5 years. The treaty includes a preface, five texts and one protocol. The main contents are as follows: when France or the Soviet Union becomes the object of aggression threat and danger of any European country, the two countries promise to hold consultations immediately in order to take measures to defend against foreign aggression in Article 1 of the Covenant of the League of Nations; When either side of France and the Soviet Union becomes the unprovoked aggression object of European countries, the two countries promise to support and assist each other immediately. In the negotiation of concluding a treaty, the two sides agreed to make another military treaty as a supplement to the political treaty, but it failed because the French government followed Britain's policy of appeasement. The Treaty of Mutual Assistance between France and the Soviet Union was signed by France and the Soviet Union under the threat of German fascist aggression after Hitler came to power. But in fact, the pact failed to play its due role in preventing and resisting German fascist aggression.

Lancome was born in France in 1935 and was a brand founded by Armand Petitjean (armand petitjean). As a world-renowned high-end cosmetics brand, Lancome is involved in many product fields, such as skin care, make-up, perfume, etc., mainly for mature women with high education level and income level, aged from 25 to 4.

The name Lancome was conceived from a castle in central France, Lancome. For the sake of pronunciation, the "S" letter in the name of the castle was replaced by a typical French long sound symbol. Because many roses are planted around Lancome Castle, which is full of romantic artistic conception, roses have become the symbol of Lancome brand. Armand, the founder of the brand, thinks that every woman is like a rose, each with its own characteristics and posture. So the brand was named after the castle, and the rose became the brand symbol of LANCOME.

Lancome's original trademark has three marks representing its series: rose, representing perfume series; Lotus stands for skin care series; Angel, representing the make-up series.
