@Entry 
@Component 
struct Father{ 
  @Provide("reviewVote") reviewVotes: number = 0; 
 
  build() { 
    Column() { 
      Son() 
      Button(`Father: ${this.reviewVotes}`) 
        ... 
    } 
  } 
}

@Component 
struct Son{ 
  build() { 
    Column() { 
      GrandSon() 
    } 
  } 
}

@Component 
struct GrandSon{ 
  @Consume("reviewVote") reviewVotes: number 
 
  build() { 
    Column() { 
      Button(`GrandSon: ${this.reviewVotes}`) 
        ... 
    }.width('100%') 
  } 
}

@Entry 
@Component 
struct Father { 
  @State reviewVotes: number = 0; 
 
  build() { 
    Column() { 
      Son({reviewVotes:$reviewVotes}) 
      Button(`Father: ${this.reviewVotes}`) 
        ... 
    } 
  } 
}

@Component 
struct Son{ 
  @Link reviewVotes: number; 
  build() { 
    Column() { 
      Grandson({reviewVotes:$reviewVotes}) 
    } 
  } 
} 
 

@Component 
struct Grandson{ 
  @Link reviewVotes: number; 
 
  build() { 
    Column() { 
      Button(`Grandson: ${this.reviewVotes}`) 
        ...
