What is the name of the brand that Lin Ruiyang and his wife founded in Zhang Ting?

It's called TST, and its main categories are skin care and makeup. In recent years, TST has also been well laid out in the field of big health, and some big health new products are often released. Moreover, Zhang Ting, the boss, has begun to enter the live broadcast industry, which shows his foresight. Hope to develop more good things!
